Given code of Test.java file:

1. package com.sampleproject.oca;

2.  

3. abstract class Animal {

4.     abstract void jump() throws RuntimeException;

5. }

6.  

7. class Deer extends Animal {

8.     void jump() { //Line n1

9.         System.out.println("DEER JUMPS");

10.     }

11.  

12.     void jump(int i) {

13.         System.out.println("DEER JUMPS TO " + i + " FEET");

14.     }

15. }

16.  

17. public class Test {

18.     public static void main(String[] args) {

19.         Animal animal = new Deer();

20.         ((Deer)animal).jump(); //Line n2

21.         ((Deer)animal).jump(5); //Line n3

22.     }

23. }

What will be the result of compiling and executing Test class?

Given code:

package com.udayan.oca;

public class Test {

    public static void main(String[] args) {

        /*INSERT*/

        arr[1] = 5;

        arr[2] = 10;

        System.out.println("[" + arr[1] + ", " + arr[2] + "]"); //Line n1

    }

}

And below statements:

1. short arr [] = new short[2];

2. byte [] arr = new byte[10];

3. short [] arr; arr = new short[3];

4. short [2] arr;

5. short [3] arr;

6. int [] arr = new int[]{100, 100};

7. int [] arr = new int[]{0, 0, 0, 0};

8. short [] arr = {};

9. short [] arr = new short[2]{5, 10};

How many above statements can be used to replace /*INSERT*/, such that on execution, code will print [5, 10] on to the console?

Consider below code of Test.java file:

1. package com.sampleproject.oca; 

2.  

3. public class Test {

4.     public static void main(String[] args) {

5.         /*INSERT*/ x = 7, y = 200;

6.         System.out.println(String.valueOf(x + y).length());

7.     }

8. }

Which of the following options, if used to replace /*INSERT*/, will compile successfully and on execution will print 3 on to the console?

Select 3 options.

Consider below code: 

1. //Test.java

2. package com.udayan.oca;

3.  

4. import java.time.LocalDate;

5.  

6. public class Test {

7.      public static void main(String [] args) {

8.          LocalDate joiningDate = LocalDate.parse("2006-03-16");

9.          System.out.println(joiningDate.withDayOfYear(29));

10.      }

11. }
