Case Insensitive String Array Comparison

Your code wont compile as you are not overriding the Object's equals method which has signature like public boolean equals(Object obj)

Also to do comparison, you could do the following in your modified equals as below:

if (array == foo.array) {
    return true;

if (array == null || foo.array == null) {
    return false;

int length = array.length;

if (foo.length != length)
        return false;

    for (int i=0; i<length; i++) {
        String string1 = array[i];
        String string2 = foo.array[i];
        if (!(string1==null ? string2==null :
            return false;
return true;

Checking if an array of string is sorted lexicographically case insensitive
Change your loop to this: for (int j=0; j<strs.length; j++){ for(int i=j+1; i<strs.length; i++){ String word = strs[j]; String check1 =word.substring(0,n); String check2= strs[i].substring(0,n); if (check1.compareToIgnoreCase(check2)>0) return false; } } As the key bit you're doing wrong is that your second loop is starting in the

C++ string() comparison with a c-string. WHY DOES THIS WORK?
The operator==() overload that kicks in is a free function in the std namespace. namespace std { bool operator==(std::string const&, std::string const&); } It takes the first argument by const& which means that a temporary is welcome. A temporary happens to be creatable using the implicit conversion constructor std::string(char const*). So, the overload applies. UPDATE As

Dart constant time string comparison
The default implementation is not constant time, but you can just create your own comparison function that compares every code unit in the String and does not short circuit: bool secureCompare(String a, String b) { if(a.codeUnits.length != b.codeUnits.length) return false; var r = 0; for(int i = 0; i < a.codeUnits.length; i++) { r |= a.codeUnitAt(i) ^ b.codeUnitAt(i); } retu
