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
