Question

Hello. I need assistance writing a method to merge two arrays and then print the new merged array. I have written the following:

import java.util.ArrayList;

public class HW1
{

public static void main(String[] args)
{

ArrayList<Integer> arr1 = new ArrayList<Integer>();

arr1.add(1);
arr1.add(4);
arr1.add(9);
arr1.add(16);
arr1.add(21);
arr1.add(33);
arr1.add(41);
arr1.add(52);
System.out.println("Array 1" + arr1);

ArrayList<Integer> arr2 = new ArrayList<Integer>();

arr2.add(4);
arr2.add(7);
arr2.add(9);
arr2.add(9);
arr2.add(20);
arr2.add(25);
arr2.add(27);
System.out.println("Array 2" + arr2);
}

I need to write a method that merges the two arrays and sorts the new array from lowest number to highest. Then I need to print the new array. The output should be the following:

1 4 4 7 9 9 9 16 20 21 33 41 52

Thank you.
