1. //Test.java

2. package com.udayan.oca;

3.  

4. class Point {

5.     static int x;

Question 3

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?

Options :
Answer: C

2. package com.sampleproject.oca;

3.  

4. public interface Flyable {

5.     static int horizontalDegree() { //Line n1

6.         return 20;

7.     }

8.  

9.     default void fly() {

10.         System.out.println("Flying at " + horizontalDegree() + " degrees."); //Line n2

11.     }

12.  

13.     void land();

14. }

1. //Aeroplane.java

2. package com.sampleproject.oca;

3.  

4. public class Aeroplane implements Flyable {

5.     public void land() {

6.         System.out.println("Landing at " + -Flyable.horizontalDegree() + " degrees."); //Line n3

7.     }

8.  

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

10.         new Aeroplane().fly();

11.         new Aeroplane().land();

12.     }

13. }
