IS this code okay?

import java.util.Stack;

public class DelimiterMatching {

    public static void main(String[] args) {

        final String input = "[(A+B)]";

        delimiterCheck(input);
 
    }

    public static void delimiterCheck(String input) {
        if (input.length() == 0) {
            System.out.println("String is empty");
        }
        Stack<Character> theStack = new Stack<>();
        for (int i = 0; i < input.length(); i++) {
            char individualChar = input.charAt(i);
            if (individualChar == '{' || individualChar == '['
                    || individualChar == '(') {
                theStack.push(individualChar);

            } else if (individualChar == '}' || individualChar == ']'
                    || individualChar == ')') {
                if (!theStack.isEmpty()) {
                    char individualCharRight = theStack.pop();
                    if ((individualChar == '}' && individualCharRight != '{')
                            || (individualChar == ')' && individualCharRight != '(')
                            || (individualChar == ']' && individualCharRight != '[')) {
                        System.out.println("Error at index " + i);
 
                    }
                }
