Lesson: 139 | Global Variables

Notes

In Apex, a class variable is a variable that is declared at the class level, meaning it is a member of the class rather than being associated with a specific instance of the class. Class variables are also referred to as static variables. They are shared among all instances of a class and can be accessed using the class name rather than an instance variable.

Here's an example of how you can declare and use a class variable in Apex:

public class MyClass {

    public static Integer myStaticVariable = 5;

    public static Integer getMyStaticVariable() {
        return myStaticVariable;
    }
}

Call the Method:

System.debug(MyClass.getMyStaticVariable());

OR

Integer result = MyClass.getMyStaticVariable();
System.debug(result);

Output: 5
