No it is illegal to call:
super.super.super.m2();
If the implementation of m2() defined by class A has to be
called from within my_class's implementation of m2(), the
following change must can be made:
class A {
public void m2() {
// call the protected implementation
m2Impl();
}
// a protected implementation of A's m2() method
// giving the implementation a protected access
// allows only subclasses to see the method
// and remains inaccessible to the rest of the world
protected void m2Impl() {
System.out.println( "A.m2() invoked" );
}
}
class B extends A {
public void m2() {
System.out.println( "B.m2() invoked" );
}
}
class C extends B {
public void m2() {
System.out.println( "C.m2() invoked" );
}
}
class my_class extends C {
public void m2() {
// call A's protected implementation
m2Impl();
}
}
public class TestSuperSuper {
public static void main( String[] args ) {
my_class mc = new my_class();
mc.m2();
}
}
Hope it helps! :-)
