Assuming this is a GUI system, You would want to use a PasswordField in JavaFX or JPasswordField in Swing.

This will allow you to type in the box and have the "Dotted" input.

You can then call .getText()(returns a String) for the PasswordField, or call .getPassword() for the JPasswordField (returns a char[]) to get the raw text values.

Alternatively, if you are using console, please see here for an answer

  • I'm using blueJ. After getting the string in dots, will the same have the external interface of the dots or the internal interface too? – user9836598 May 23 '18 at 19:10
  • @user9836598 On the User interface, the values of the password field will remain dotted, but you can use the "non-dotted" values within your program as plain text(no dots). – HamishD May 23 '18 at 19:13
