Overriding and redefining

[Dheepan Thangavelu]

Hi All
What is the Diff between Overriding and redefining a method.

Rgds,

No difference.
Overriding is redefining a method previously implemented in a parent class to change its behavior.

I don't think "redefine" has a specific meaning in OO circles. If you mean override it will be clearer to say override.

Or were you thinking of static methods? Static methods can't be overridden, but
they can be hidden:

class A {
    public void f() {System.out.println("A.f");}
    public static void g() {System.out.println("A.g");}
    public static void h() {System.out.println("A.h");}
    public void k() {System.out.println("A.k");}
}
 
class B extends A {
    public void f() {System.out.println("B.f");}
    public static void g() {System.out.println("B.g");}
    void h() {System.out.println("B.h");}
    static void k() {System.out.println("B.k");}
}

Here, f is an example of overriding, g is an example of hiding,
and h and k are syntax errors. Quiz: what output does this produce?

A a = new B();
a.g();
