Check if two Strings are Anagrams of each other in java 8?

There are following way to Check if two Strings are Anagrams of each other in java 8.

• Here str1.split(“”) method splits the string into an array of substrings and stream this array using Arrays.stream() method.
• In map(a->a.toUpperCase()) we convert all characters to uppercase.
• From sorted () method sort the characters in ascending order.
• After Collectors.joining() method collect all characters into string.
• Next validate if r1 is equals to r2 or not. if it equals then String is Anagrams otherwise not.

import java.util.Arrays;
import java.util.stream.Collectors;

public class CheckAnagram {
	public static void main(String[] args) {
		String str1 = "listen";
		String str2 = "silent";
		String r1 = Arrays.stream(str1.split("")).map(a -> a.toUpperCase()).sorted().collect(Collectors.joining());
		String r2 = Arrays.stream(str2.split("")).map(a -> a.toUpperCase()).sorted().collect(Collectors.joining());

		if (r1.equals(r2)) {
			System.out.println("it is a anagram string");
		} else {
			System.out.println("it is a not anagaram string");
		}
	}
}

Output :-
it is a anagram string
