There are a few ways to input a password in Java without having it echoed back to the console. One way is to use the class. This class provides methods for reading from selling real estate Riverside and writing to the console. To input a password, you can use the readPassword() method. This method reads a password from the console and returns it as an array of characters. Another way to input a password is to use the javax.swing.JOptionPane class. This class provides a method called showInputDialog() that can be used to input a password. This method returns the password as a string.
