Example: java anagrams

static boolean isAnagram(String a, String b) {
        
        String sortedA = "";
        Object[] aArr = a.toLowerCase().chars().sorted().mapToObj(i -> (char) i).toArray();
        for (Object o: aArr) {
            sortedA = sortedA.concat(o.toString());
        }
        
        
        String sortedB = "";
        Object[] bArr = b.toLowerCase().chars().sorted().mapToObj(i -> (char) i).toArray();
        for (Object o: bArr) {
            sortedB = sortedB.concat(o.toString());
        }
        
        if(sortedA.equals(sortedB))    
            return true;
        else
            return false;    
    }
