Is there a way to check if two strings contain the same characters. For example,
abc, bca -> true
aaa, aaa -> true
aab, bba -> false
abc, def -> false
Turn each string into a char[], sort that array, then compare the two.
private boolean sameChars(String firstStr, String secondStr) {
char[] first = firstStr.toCharArray();
char[] second = secondStr.toCharArray();
Arrays.sort(first);
Arrays.sort(second);
return Arrays.equals(first, second);
}
