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:

<         


        

Answer 1

This method does the trick.

boolean contains(char c, char[] array) {
    for (char x : array) {
        if (x == c) {
            return true;
        }
    }
    return false;
}

Example of usage:

class Main {

    static boolean contains(char c, char[] array) {
        for (char x : array) {
            if (x == c) {
                return true;
            }
        }
        return false;
    }

    public static void main(String[] a) {
        char[] charArray = new char[] {'h','e','l','l','o'};
        if (!contains('q', charArray)) {
            // Do something...
            System.out.println("Hello world!");
        }
    }

}

Alternative way:

if (!String.valueOf(charArray).contains("q")) {
    // do something...
}
