JPasswordField
single line display of text on the screen similar to a JTextField especially for keying passwords. Instead of presenting the result as a String JPasswordField gives you a char[] which can be erased after use. With a String result, the password could lie around in RAM waiting to be GCed, and potentially scavenged by someone snooping on the swapfile. By default it echos * so someone watching over the keyer’s shoulder could not read the password. Further someone snooping on the screen RF emissions could not pick up the password.
