Private and Dynamic Method Binding

Since a private method can not be called from the child, when an inherited method (foo) calls a private method (Parent.bar), the parent private method is always the one called 

class Parent
   {
   public void foo() 
      { 
      bar(); 
      };

   private void bar() 
      { 
      System.out.println( "Parent bar"); 
      };
   }

class Child extends Parent
   {
   public void bar() 
      { 
      System.out.println( "Child bar");
      };
   }

class Test 
{
   public static void main( String args[] )
   {
   Parent trouble = new Child();
   trouble.foo();
   }
}
Output
Parent bar
