How can I make startswith function in Java

public static boolean startsWith(String x, String y) {
    int check = 0;
    for (int i = 0; i < y.length(); i++) {
        if (y[i] == x[i]) {
            check += 1;
        }
        if (check == y.length()) {
            return true;
        }
        return false;
    }
}

I tried to make startswith function alternative but it’s not working.
I put all bracelets on the right places but it still gives me an error.

>Solution :

public static boolean startsWith(String s, String prefix) {
    if (prefix.length() <= s.length()) {
        String sub = s.substring(0, prefix.length());
        return sub.equals(prefix);
        //Alternatively
        /*
        for (int i = 0; i < sub.length(); i++) {
            if (sub.charAt(i) != prefix.charAt(i)) {
                return false;
            }
        }
        return true;
        */
    }
    return false;
}
