Question
class A {
final public int calculate(int a, int b) { return 1; }
}
class B extends A {
public int calculate(int a, int b) { return 2; }
}
public class output {
public static void main(String args[])
{
B object = new B();
System.out.print("b is " + b.calculate(0, 1));
}
}
What is the output of this program?
class A {
final public int calculate(int a, int b) { return 1; }
}
class B extends A {
public int calculate(int a, int b) { return 2; }
}
public class output {
public static void main(String args[])
{
B object = new B();
System.out.print("b is " + b.calculate(0, 1));
}
}
