How can I see if part of a word is contained in an array?

Question

For instance, let's say I have the following array of app names:

{"Math Workshop", "Math Place", "Mathematics", "Angry Birds"}

I want to scan this array for any elements that contains the word math. How can I do that?

Maybe this question can help? http://stackoverflow.com/questions/1128723/in-java-how-can-i-test-if-an-array-contains-a-certain-value — Naga, Jun 20 '13 at 13:08
@user2062810 That would help if the OP was seeking whole words, not partial words. — Duncan Jones, Jun 20 '13 at 13:19
I don't understand why this is closed. Yes, it's a simple question and yes some prior research should have happened. But I can easily imagine other people seeking an answer to this problem. I'm voting to re-open. At the very worst, it should be closed as a duplicate if anyone kind find one. — Duncan Jones, Jun 20 '13 at 14:33

Try the following code:

String[] appNames = {"Math Workshop", "Math Place", "Mathematics", 
    "Angry Birds"};

for (String name: appNames) {
  if (name.toLowerCase().contains("math")) {
    // TADA!!!
  }
}

Since contains() is case-sensitive, you will need to convert your string to lower case if you want a case-insensitive match.

And it isn't a bad idea to pass the `Locale` to `toLowerCase()`, too – Lukas Eder Jun 20 '13 at 13:51

for (String title : array) {
    if (title.toLowerCase().indexOf("math") != -1). {
        return true;
    } 
}
return false;
