Question

How to check if two strings are anagram (same letters different words) in Java

Answer 1

import java.util.Arrays; 
 
public class Test { 
    
    static boolean isAnagram(char[] s1, char[] s2) { 
        int lens1 = s1.length; 
        int lens2 = s2.length; 
    
        if (lens1 != lens2) 
            return false; 
    
        Arrays.sort(s1); 
        Arrays.sort(s2); 
    
        for (int i = 0; i < lens1; i++) 
            if (s1[i] != s2[i]) 
                return false; 
    
        return true; 
    } 
    
    public static void main(String args[]) 
    { 
        char s1[] = { 'j', 'a', 'v', 'a' }; 
        char s2[] = { 'v', 'a', 'j', 'a' }; 
          
        if (isAnagram(s1, s2)) {
            System.out.println("Anagram"); 
        }
        else {
            System.out.println("Not Anagram"); 
        }
    } 
} 
  
  
  
/*
run:
  
Anagram
  
*/
