In Java, how can I determine if a char array contains a particular character?

Question

Here\'s what I have:

char[] charArray = new char[] {\'h\',\'e\',\'l\',\'l\',\'o\'};

I want to write something to the effect of:

<

Here's a variation of Oscar's first version that doesn't use a for-each loop.

for (int i = 0; i < charArray.length; i++) {
    if (charArray[i] == 'q') {
        // do something
        break;
    }
}

You could have a boolean variable that gets set to false before the loop, then make "do something" set the variable to true, which you could test for after the loop. The loop could also be wrapped in a function call then just use 'return true' instead of the break, and add a 'return false' statement after the for loop.
