How to check two sentences or strings are Anagram using String class

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

public class CheckAnagram {

	public static void main(String [] args) {

		Scanner inpStr=new Scanner(System.in);
		System.out.println("Enter an input first line of strings");
		String str=inpStr.nextLine();

		//Converting the input sentence to sequence of characters array in the same order
		char[] str1Chars=str.toCharArray();

		//Sorting the characters array including with spaces if any available
		Arrays.sort(str1Chars);
		System.out.println("Enter an input second line of strings");
		str=inpStr.nextLine();
		char[] str2Chars=str.toCharArray();
		Arrays.sort(str2Chars);
		inpStr.close();

		//Compare the two sorted character array strings, excluding the spaces after converting into lower case for Anagram check
		if (String.valueOf(str1Chars).trim().toLowerCase().contentEquals(String.valueOf(str2Chars).trim().toLowerCase()))
			System.out.println("Both Line of Strings are Anagram");
		else
			System.out.println("Both Line of Strings are Not Anagram");
	}
