Annotations

An Apex annotation modifies the way a method or class is used, similar to annotations in Java.

Annotations are defined with an initial @ symbol, followed by the appropriate keyword. To add an annotation to a method, specify it immediately before the method or class definition. For example:

global class MyClass {
     @future
     Public static void myMethod(String a)
     {
          //long-running Apex code 
    
     }
}
