Given the code fragment:

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

package com.udayan.oca;

import java.util.ArrayList;

import java.util.List;

public class Test {

     public static void main(String[] args) {

         List list = new ArrayList<>();

         list.add(100);

         list.add(7);

         list.add(50);

         list.add(17);

         list.add(10);

         list.add(5);

         list.removeIf(a -> a % 10 == 0);

         System.out.println(list);

     }

}

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?
