Question
What will be the output of the following Java code? class Codetantra { final public int output(int x, int y) { return 1; } } class Program extends Codetantra { public int output(int x, int y) { return 2; } } public class result { public static void main(String args[]) { Program object = new Program(); System.out.print("y is " + y.output(0, 1)); } }Optionsy is : 0y is : 1Compilation ErrorAn exception is thrown at runtime
Solution
The output of the Java code will be a Compilation Error. This is because the method "output" in the class "Codetantra" is declared as final. The final keyword in Java is used to restrict the user. Once a method is declared final, it cannot be overridden by the inheriting class. In this case, the class "Program" is trying to override the final method "output" from the class "Codetantra", which is not allowed. Hence, a compilation error will occur.
