How to access methods from other classes in apex

Hi,

    How I can access methods from different class ( static / through instance variable ).
    e.g.
           I need something like this - 
public class A {
      public void callA(){
          :
      }
   }

public class B {
      public void callB() {
           A obj = new A();
           obj.callA();
      }
   }

Thanks,
Abhishek

As long as the methods are public or global, the syntax you show in your example will work for instance methods.  For static methods, it would be similar:

public class A {
    public void callA(){}
}

public class B {
    public void callB() {
           A.callA();
    }
}

James forgot to add `static` for the `callA` method :)

public static void callA()

Hi Abhishek,

For static method ina class,

public class sample{
    public static void method(){
       System.debug('Testing');
    }
}
In Annonymous window,  we call as sample.method(); ,then testing output will be diaplayed.

If we access any method except static,then we use

public class sample1{
    public  void method1(){
       System.debug('Access');
    }
}
In Annonymous window, First create object for this class with the help of new operator and then call method with object.

sample1  sam= new sample1();
sam.method1();
