a. Write a method to subtract two one-dimensional integer arrays and return the result, assuming the two arrays are of the same size. For example, the addition result of {4, 5, 1) and (-1, 2, 9) is (5, 3, -8). The implementation of the method should be general so that it can return the subtraction result for any two arrays of the same size. The method signature is given as follows: public static int[] subtract (int[] a, int[] b) Write a main method in the same file that: • Prompts the user to enter the number of integers (the size of the arrays), Initializes two int arrays by user's inputs using two for loops, Invokes the subtract method, Displays the subtracted array contents using another for loop. A sample output: Pleaes input the number of integers: 3 Pleaes input the integers for the first array: Enter a number: 4 Enter a number: 5 Enter a number: 1 Pleaes input the integers for the second array: Enter a number: -1 Enter a number: 2 Enter a number: 9 The subtracted array is: 53-8

Question

Need help with 2d array problem and getting the display result asked in the problem.

Write a method to subtract two one-dimensional integer arrays
and return the result, assuming the two arrays are of the same size.
For example, the addition result of {4, 5, 1} and {-1, 2, 9) is (5, 3,
-8). The implementation of the method should be general so that it can
return the subtraction result for any two arrays of the same size. The
method signature is given as follows:
public static int[] subtract (int[] a, int[] b)
Write a main method in the same file that:
Prompts the user to enter the number of integers (the size of
the arrays),
Initializes two int arrays by user's inputs using two for loops,
Invokes the subtract method,
Displays the subtracted array contents using another for loop.
A sample output:
Pleaes input the number of integers: 3
Pleaes input the integers for the first array:
Enter a number: 4
Enter a number: 5
Enter a number: 1
Pleaes input the integers for the second array:
Enter a number: -1
Enter a number: 2
Enter a number: 9
The subtracted array is:
53-8
