Locking folder with cacls not working

So I've been trying to make an app that would lock a folder. It was working just fine until I added a jtextfield where you could specify the path of the folder and the name of the folder.

This is the array to lock and unlock the folder:

String[] lock = new String[]{"cmd.exe", "/C", "cd \"" + String.valueOf(path.getText())+ "\" && dir", "&", "cacls", String.valueOf(name.getText()), "/e", "/c", "/d", "%username%"};
String[] unlock = new String[]{"cmd.exe", "/C", "cd \"" + String.valueOf(path.getText())+ "\" && dir", "&", "cacls", String.valueOf(name.getText()), "/e", "/c", "/g", "%username%:f"};

And this is the action listener for the two buttons:

block.addActionListener(e -> {
        if (password.getText().toString().equals(passwordText)) {
            try {
                Process p = Runtime.getRuntime().exec(lock);
            } catch (IOException e1) {
                e1.printStackTrace();
            }
        } else {
            password.setText("");
            passwordLabel.setText("Incorrect password");
            failed.get().start();
        }


    });
unblock.addActionListener(e -> {
        if (password.getText().toString().equals(passwordText)) {
            try {
                Process p = Runtime.getRuntime().exec(unlock);
            } catch (IOException e1) {
                e1.printStackTrace();
            }
        } else {
            password.setText("");
            passwordLabel.setText("Incorrect password");
            failed.get().start();
        }

    });

When I was specifying directly the path and name it was working fine but now it doesn't do anything. (Sorry for my bad english. Feel free to correct me)

Your error was to initialize the variables lock and unlock before there is a valid value in the JTextFields (at that time, the fields value are empty strings or null). Instead, you should initialize them just before calling Runtime.exec.
