[qtd (Đỗ Trung Quân)]

Let’s have a discussion about this problem and get the answer here http://www.indiabix.com/online-test/java-programming-test/61

1. What will be the output of the program?

class A 
{
    final public int GetResult(int a, int b) { return 0; } 
} 
class B extends A 
{ 
    public int GetResult(int a, int b) {return 1; } 
} 
public class Test 
{
    public static void main(String args[]) 
    { 
        B b = new B(); 
        System.out.println("x = " + b.GetResult(0, 1));  
    } 
}

• A. x = 0
• B. x = 1
• C. Compilation fails.
• D. An exception is thrown at runtime.
