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

Question

Can anyone help me how I can able to check whether an array contains a particular characters or not. I want to do something like this:

if(!charArray contains 'q'){

     break;

}

Any help would be appreciated.

Basically, you can use the below code snippet to use the contains method like this:

boolean contains = false;

for (char c : charArray) {

    if (c == 'q') {

        contains = true;

        break;

    }

}

if (!contains) {

    // do something

}

Also, you can use different method like indexOf():

if (new String(charArray).indexOf('q') == -1) {

    // do something

}

I hope this will help.
