How can i check if a string matches String array

How can i check if a string matches any of elements in string array.

Suppose a String array contain {abcdef, ghijkl} Comparing it with a string "abc" should return the first value

If have been using stringArray.contains(string) method but it seems to work only if the complete string matches. I need to get the result even if the string partially matches

Any help would be appreciated

You can use indexOf method:

String[] contains(String[] stringArray, String target) {
    String[] result = new String[2];

    for(int index = 0; index < stringArray.length; index++) {
        String current = stringArray[index];
        if (s.indexOf(target) >= 0) {
            result[0] = current;
            result[1] = String.valueOf(index);
        }
    }
}

Streams come in handy:

Arrays.stream(stringArray)
  .filter(s -> s.contains(stringToSearch))
  .findFirst();

Of course, your requirements boil down to: find the first string in the array that starts with the search string. But actually your requirements are a bit unclear, so you should apply the filter as required. There is a big difference between contains() and startsWith() for example!

No method without using a loop. I understand you might be looking for some implementation which does not need a self written loop. But you have to loop.
