Java Check if multiple strings are empty-CodePudding

I am trying to add a User into a LinkedList using Java, but I am wondering if there is a shorter way to check if multiple strings are empty instead of using if statements everytime I input a new string

This is the method I came up with

    public void addUser() {
        int error = 0;
        
        do {
            Users user = new Users();
            String name = JOptionPane.showInputDialog(null, "Enter your name");
            if (name.isEmpty()) {
                error = 1;
            } else {
                String password = JOptionPane.showInputDialog(null, "Enter a password");
                if (password.isEmpty()) {
                    error = 1;
                } else {
                    // more string inputs
                }
            }

        } while (error != 0);
    }

CodePudding user response：

Implement a separate method to read the input data until a valid string is provided and call this method with custom prompt:

private static String readInput(String prompt) {
    String input;
    do {
        input = JOptionPane.showInputDialog(null, prompt);
    } while (input == null || input.isEmpty());
}

public void addUser() {
    String name = readInput("Enter your name");
    String password = readInput("Enter a password");
// ...
    User user = new User(name, password, ...);
// ...
}
