How to check two sentences or strings are Anagram

import java.util.Arrays;
import java.util.Scanner;

//Define the functional interface with SAM 'checkForAnagram'
interface Anagram {
	public void checkForAnagram(String str1, String str2);
}

public class AnagramCheck {

	public static void main(String[] args) {

		Scanner inpStr = new Scanner(System.in);

		/* Define the Lambda expression for the user defined functional interface */
		Anagram Ag = ((str1Val, str2Val) -> {

			// Converting the both input strings to sequence of characters array
			char[] str1Chars = str1Val.toLowerCase().toCharArray();
			char[] str2Chars = str2Val.toLowerCase().toCharArray();

			// Sorting the characters of two arrays including with spaces, if any
			Arrays.sort(str1Chars);
			Arrays.sort(str2Chars);

			/*
			 * Compare the two sorted character array strings, excluding the spaces, after
			 * converting into lower case for Anagram check
			 */
			if (String.valueOf(str1Chars).trim().contentEquals(String.valueOf(str2Chars).trim()))
				System.out.println("The strings '" + str1Val + "' and '" + str2Val + "' are Anagram");
			else
				System.out.println("The strings '" + str1Val + "' and '" + str2Val + "' are not Anagram");
		});

		System.out.println("Enter an input first line of strings");
		String str1 = inpStr.nextLine();
		System.out.println("Enter an input second line of strings");
		String str2 = inpStr.nextLine();

		// Calling the functional interface with String arguments
		Ag.checkForAnagram(str1, str2);
		Ag.checkForAnagram("sample", "amples");
		Ag.checkForAnagram("Clears", "Pearls");
		inpStr.close();
