Class Apex: Master Your Game in Apex Legends
Are you tired of getting eliminated early in Apex Legends matches? Do you want to improve your chances of survival in King’s Canyon? Then it’s time to learn about the class apex tier list. Each legend in Apex Legends has their own unique abilities, but some legends are simply better and more versatile than others. In this section, we’ll break down the top characters in the class apex tier list and give you advice on how to play them effectively.
S Tier: Wraith and Pathfinder
Wraith and Pathfinder are the top picks in Apex Legends. Wraith’s tactical ability makes her invulnerable for a limited time, allowing her to dodge incoming damage or escape sticky situations. Pathfinder, on the other hand, has an incredibly useful grappling hook that can be used to reach new heights or quickly evade an enemy’s attack. Both characters are ideal for players who have a more aggressive playstyle, as their abilities allow them to quickly engage on enemies or retreat when needed.
A Tier: Lifeline and Bangalore
Lifeline and Bangalore are also popular picks due to their abilities to support their teammates in battle. Lifeline is a combat medic who can quickly revive downed allies, and her ultimate ability calls in a care package with high-tier loot. Bangalore, on the other hand, can create a smoke screen to obscure enemy vision and call in precision airstrikes to deal massive damage.
B Tier: Mirage and Octane
Mirage and Octane are both legends that require a bit more skill to play effectively, but can greatly reward players who master their abilities. Mirage’s tactical ability creates a decoy that can distract enemies or bait them into traps, while his ultimate cloaks him and his teammates for a limited amount of time. Octane, meanwhile, can use a stim pack to greatly increase his speed or jump pad to vertically reposition himself. Both characters are great choices for players who like to play mind games with their enemies.
C Tier: Caustic and Gibraltar
Caustic and Gibraltar are two legends that are rarely seen in high-level play due to their large hitboxes and slower movement speed. However, they can still be effective in the right hands. Caustic can deploy toxic gas traps that damage and slow enemies, making it easier for him to pick them off or escape. Gibraltar, on the other hand, has a shield that can absorb incoming damage and an ultimate ability that calls in a bombardment of missiles. Both legends are ideal for players who prefer a defensive playstyle, but may require a bit more strategic positioning to be effective.
In conclusion, mastering the class apex tier list and understanding each legend’s unique abilities can greatly improve your chances of winning in Apex Legends. Whether you prefer a more aggressive or defensive playstyle, there’s a legend out there for you. So get out there, experiment with different characters, and see which one fits your playstyle the best. Happy hunting, Legends!
What is a Set Apex
Apex is a powerful programming language used in Salesforce that enables developers to build custom applications and integrations with other systems. One of the most commonly used types of data structures in Apex is a Set.
Introduction to Sets
A Set is an unordered collection of elements that does not allow duplicates. Elements in a Set can be of any data type, including primitive data types, collections, sObjects, and user-defined types. By definition, a Set contains only unique elements, which makes it an ideal choice when you need to keep track of a list of unique values.
Benefits of Using a Set
Sets offer several benefits over other types of data structures in Apex. First, Sets are highly efficient when it comes to adding, removing, and querying elements. Since Sets do not allow duplicates, adding or removing elements to a Set ensures that each element is unique, which can streamline your coding process.
Another advantage of Sets is that they can be used to perform set operations such as intersection, union, and difference. These set operations can be useful when comparing two or more Sets to determine the common elements or unique elements between them.
Creating a Set in Apex
To create a Set in Apex, use the following syntax:
Set
For example, to create a Set of integers, you would use:
Set
Once you have created a Set, you can add elements to it using the add() method:
myset.add(1);
myset.add(2);
myset.add(3);
Sets are an important data structure in Apex that can help you streamline your coding process and perform set operations efficiently. By creating Sets of unique elements, you can ensure that your code is optimized for performance and accuracy. With these benefits in mind, it’s clear that Sets should be a core part of every Apex developer’s toolkit.
List Methods in Apex
If you’ve spent any amount of time working with Apex, you’ve likely encountered the list data type. Lists in Apex are powerful tools for storing and manipulating data, and there are several helpful methods available to help you work with lists more easily.
Adding Elements to a List
One of the most common operations when working with lists is adding elements to the list. You can add elements to a list using the add method:
List
myStrings.add(‘Hello’);
myStrings.add(‘World’);
In this example, we create a new list of strings and add two elements to it using the add method.
Removing Elements From a List
Similarly, you can remove elements from a list using the remove method. The remove method takes an index as its argument and removes the element at that index from the list. For example:
List
myStrings.remove(0); // Removes the ‘Hello’ element
In this example, we create a new list of strings and use the remove method to remove the first element of the list.
Sorting a List
If you have a list that needs to be sorted, you can use the sort method. The sort method sorts the elements of the list in ascending order by default, but you can also provide a custom comparator to sort the list in a different order. For example:
List
myNumbers.sort();
In this example, we create a new list of integers and use the sort method to sort the elements of the list in ascending order.
Checking if an Element Exists in a List
If you need to check if an element exists in a list, you can use the contains method. The contains method returns a boolean value indicating whether or not the list contains the specified element. For example:
List
Boolean containsHello = myStrings.contains(‘Hello’); // True
Boolean containsGoodbye = myStrings.contains(‘Goodbye’); // False
In this example, we create a new list of strings and use the contains method to check if the list contains the ‘Hello’ and ‘Goodbye’ elements.
These are just a few of the many methods available for working with lists in Apex. By using these methods and others like them, you can create more powerful and efficient Apex code.
Custom Setting Apex Example
Custom settings allow you to create custom fields and variables that can be used within your Apex code. They can help you to create more flexible and dynamic applications. Here are some examples of how to use custom settings in your Apex code.
Define Custom Setting
Before using a custom setting, you need to create it. You can create a custom setting using the Custom Settings page in Salesforce. Once you have created a custom setting, you can refer to it in your Apex code.
Access Custom Setting Data in Apex
To access the data in a custom setting, you can use the following code:
CustomSetting__c myCustomSetting = CustomSetting__c.getValues(‘CustomSettingName’);
String customSettingValue = myCustomSetting.CustomSettingValue__c;
This code retrieves the CustomSetting__c object with the specified name and assigns the value of the CustomSettingValue__c field to the customSettingValue variable.
Use Custom Setting Data in Apex
Once you have retrieved the value from a custom setting, you can use it in your Apex code. Here’s an example of how to use a custom setting in a query:
List
This code retrieves all contacts created after the start date specified in the MyCustomSetting custom setting.
Modify Custom Setting Data in Apex
You can modify the data in a custom setting by updating the CustomSetting__c object and using the upsert method. Here’s an example of how to modify a custom setting:
CustomSetting__c myCustomSetting = CustomSetting__c.getValues(‘MyCustomSetting’);
myCustomSetting.CustomSettingValue__c = ‘New Value’;
upsert myCustomSetting;
This code updates the value of the CustomSettingValue__c field in the MyCustomSetting custom setting to ‘New Value’.
In conclusion, custom settings are an excellent way to store configuration data and constants in your Salesforce application. They are easy to create and modify in the Custom Settings page, and they can be accessed and modified in your Apex code using simple syntax. Try using custom settings in your next Salesforce project to make your code more dynamic and flexible.

Set Apex Variable Value from JavaScript
When it comes to Apex and JavaScript, we need to figure out how to communicate between the two so that we can perform necessary actions on the Salesforce platform. One of the most fundamental things we need to understand is how to set the Apex variable value from JavaScript.
Using Visualforce Binding
One of the easiest ways to transfer values between JavaScript and Apex is by using Visualforce binding. Visualforce bindings provide a simple way to pass data between the server-side and client-side code. Let’s have a look at the code snippet below.
“`html
“`
In the code above, we are using the apex:outputText tag to bind the Apex variable to a tag. We can now access the tag in JavaScript and set its value.
javascript
document.getElementById(“apexValue”).innerHTML = jsName;
Using JavaScript Remoting
Another powerful way to communicate between JavaScript and Apex is by using JavaScript remoting. It allows us to execute Apex methods from JavaScript and retrieve the results, all without requiring a page refresh. Have a look at the code snippet below.
javascript
Visualforce.remoting.Manager.invokeAction(
‘{!$RemoteAction.SampleController.setApexValue}’,
jsValue,
function(result, event) {
if (event.status) {
console.log(result); // Success!
} else {
console.log(event.message); // Error!
}
}
);
In the code above, we are invoking the Apex method setApexValue from JavaScript by using Visualforce.Remoting.Manager.invokeAction. We can then catch the result in the callback function. This method is particularly useful for more complex scenarios where we need to execute Apex code from the client-side.
Setting the Apex variable value from JavaScript is a fundamental aspect of Salesforce development. While there are various ways to achieve this, using Visualforce binding and JavaScript remoting are the most popular and straightforward methods. By following these examples, you should now be able to set the Apex variable value from JavaScript efficiently.
How to retrieve an element from an Apex set
In Apex, a set is an unordered collection of elements of the same data type that do not contain any duplicates. Retrieving an element from a set is a common operation that you might need to perform in your Apex code. In this section, we’ll go over the different methods you can use to retrieve an element from an Apex set.
Using the contains() method
The contains() method checks whether a specified element is present in a set. If the element is present, the method returns true; otherwise, it returns false. You can use the contains() method to check if an element exists in a set before retrieving it.
Here’s an example of how you can use the contains() method to retrieve an element from a set:
apex
Set
if (fruits.contains(‘Banana’)) {
String myFruit = ‘Banana’;
// do something with myFruit
}
Using the iterator() method
The iterator() method returns an iterator that allows you to traverse the set and retrieve its elements one by one. You can use the iterator() method to iterate over the set and retrieve the desired element.
Here’s an example of how you can use the iterator() method to retrieve an element from a set:
apex
Set
Iterator
while (it.hasNext()) {
String myFruit = it.next();
if (myFruit == ‘Banana’) {
// do something with myFruit
}
}
Using the toArray() method
The toArray() method returns an array containing all the elements in a set. You can use the toArray() method to retrieve all the elements in the set and then access the desired element by its index.
Here’s an example of how you can use the toArray() method to retrieve an element from a set:
apex
Set
List
String myFruit = fruitList[1]; // retrieves the second element (Banana)
// do something with myFruit
In conclusion, there are different methods you can use to retrieve an element from an Apex set, including the contains() method, the iterator() method, and the toArray() method, each with its advantages. By knowing which method is best suited for your use case, you can easily retrieve the desired element from your set.
