Write a Java program to check whether two strings are anagram or not?

Two strings are called anagrams if they contain same set of characters but in different order.

"keep ? peek", "Mother In Law - Hitler Woman".

File: AnagramString .java

import java.util.Arrays;
 
public class AnagramString {
	static void isAnagram(String str1, String str2) {
		String s1 = str1.replaceAll("\\s", "");
		String s2 = str2.replaceAll("\\s", "");
		boolean status = true;
		if (s1.length() != s2.length()) {
			status = false;
		} else {
			char[] ArrayS1 = s1.toLowerCase().toCharArray();
			char[] ArrayS2 = s2.toLowerCase().toCharArray();
			Arrays.sort(ArrayS1);
			Arrays.sort(ArrayS2);
			status = Arrays.equals(ArrayS1, ArrayS2);
		}
		if (status) {
			System.out.println(s1 + " and " + s2 + " are anagrams");
		} else {
			System.out.println(s1 + " and " + s2 + " are not anagrams");
		}
	}
 
	public static void main(String[] args) {
		isAnagram("Keep", "Peek");
		isAnagram("Mother In Law", "Hitler Woman");
	}
}

Output:

Keep and Peek are anagrams
MotherInLaw and HitlerWoman are anagrams
