Creating Password Field by Using JPasswordField Class

In this tutorial, we are going to show you how to create password field using JPasswordField class.

The password field allows user to enter password. For security reason, password field displays echo characters instead of the password itself. The default echo character is (*).

In Java swing, to create a password field you use JPasswordField class. You can assign a different echo character other than the default one (*) using setEchoChar() method. You can get the password using getPassword() method. If you use copy() orcut() method, you will get nothing but beep sound.

The following table illustrates some common uses constructors of the JPasswordField class:
JPasswordField Constructors Meaning
public JPasswordField () Creates a new password field.
public JPasswordField (Document doc, String text, int columns) Creates a new password field with given document and number of columns.
public JPasswordField(String text) Creates a new password field with a given text.
public JPasswordField(int columns) Creates a new password field with a given columns.

Example of using JPasswordField class

In this example, we will use JPasswordField class to create a simple password field.
Java JPasswordField

The object of a JPasswordField class is a text component specialized for password entry. It allows the editing of a single line of text. It inherits JTextField class.
JPasswordField class declaration

JPasswordField is a lightweight component that allows the editing of a single line of text where the view indicates something was typed, but does not show the original characters. You can find further information and examples in How to Use Text Fields, a section in The Java Tutorial.

NOTE: By default, JPasswordField disables input methods; otherwise, input characters could be visible while they were composed using input methods. If an application needs the input methods support, please use the inherited method, enableInputMethods(true).
Swing is not thread safe. For more information see Swing's Threading Policy.
