Anonymous class

[Milan Sutaria]

    class B{
 
static void go() {}
 
public static void main(String[] args) {
Thread t = new Thread(){
public void run(){go();}
};
 
}
 
}
 

Inside main method an anonymous class is created which is a sublclass of Thread class. How can it access the go method without the class name ( B.go() )?

Inner classes have access to all members of the enclosing outer class.

Although you have got your answer but still I would like to explain it here
As you might know All Inner classes are compiled into top level classes.
When an anonymous class accesses the members of its enclosing class at compile time the compiler will add the name of the enclosing class at the statement where you are accessing the enclosing class member(static).
So your code after compilation will become-

class B
{
  static void go() {}
 
  public static void main(String[] args)
  {
    Thread t = new Thread$1();
  }
}
class B$1 extends Thread
{
   public void run()
   {
         [B]B[/B].go();
   }
}
