How do I find words that only contain/consist of a given char sequence

anagram, java

Solution

Without regular expressions:

public static boolean sameCharacters(String left, String right) {
    return sortCharacters(left).equals(sortCharacters(right));
}

private static String sortCharacters(String s) {
    final char[] chars = s.toCharArray();
    Arrays.sort(chars);
    return String.valueOf(chars);
}

UPDATE: better performing version (thanks to user384706):

public static boolean sameCharacters(String left, String right) {
    return Arrays.equals(sortCharacters(left), sortCharacters(right));
}

private static char[] sortCharacters(String s) {
    final char[] chars = s.toCharArray();
    Arrays.sort(chars);
    return chars;
}

Problem

I wish to loop through a dictionary file and find words that contain only the given characters Example dgo Desired results: dog, god NOT words that contain (within them) the given characters I am working with the following code: ``` while((dictionaryWord = br_.readLine()) != null) { if(dictionaryWord.contains(getWord())) System.out.println(dictionaryWord); } ``` But this gives me all words which contain the given characters -- NOT DESIRED
