DONT NEED HARDCORE.

I need whole program and its for userinput.

Java language.

Write a method

public static boolean sameElements(int[] a, int[] b)

that checks whether two arrays have the same elements in some order, with the same multiplicities. For example,

1 4 9 16 9 7 4 9 11

and

11 1 4 9 16 9 7 4 9 would be considered identical, but

1 4 9 16 9 7 4 9 11
