Johhny did the method overriding of mA() method in class B as shown below. What exactly did he do wrong?

Question

public class A {

public double mA() {

// code

}

}

public class B extends A {

private double mA() {

// code

}

}

Answer 1

//Base class abstract

public abstract class A

{

public abstract double mA();

}

class B extends A

{

public double mA()

{

System.out.println("B.mA ");

return 0;

}

public static void main(String args[])

{

B b= new B();

b.mA();

}

}
