  • Question 5
    • The last statement inside main(String []) method, increments value of i, which means it is not effectively final and hence compilation error.

      //Test.java

      package com.udayan.ocp;

       

      class Player {

          String name;

          int age;

          Player() {

              this.name = "Virat";

              this.age = 29;

          }

          

          public int hashCode() {

              return 100;

          }

      }

       

      public class Test {

          public static void main(String[] args) {

              System.out.println(new Player());

          }

      }

      Hexadecimal representation of 100 is 64.

      Which of the following option is correct?
