Question

import java.util.Scanner;
import java.util.Arrays;
public class Anagram {

// Returns a copy of the string in sorted order.
public static String sort(String s) {
    char [] sortString = s.toCharArray();
    Arrays.sort(sortString);
    String sorted = String.valueOf(sortString);
    return s;


}

public static void main(String[] args) {

    Scanner in = new Scanner(System.in);

    System.out.print("Enter line: ");
    String line = in.next();
    String lineString = line.replaceAll("[^0-9A-Za-z]", "");
    String lineSortString = sort(lineString);

    System.out.print("Enter anagram: ");
    String anagram = in.next();
    String anagramString = anagram.replaceAll("[^0-9A-Za-z]", "");
    String anagramSortString = sort(anagramString);

    if(lineSortString == anagramSortString){
        System.out.println("\nAnagram!");
    }else{
        System.out.println("\nNot a anagram.");
    }

 public static String sort(String s) {
    char [] sortString = s.toCharArray();
    Arrays.sort(sortString);
    String sorted = String.valueOf(sortString);
    return sordet;//这样改试试
}
