Warning: serialized objects of this class will not be compatible with future swing releases. The current serialization support is appropriate for short term storage or RMI between Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

columns - the number of columns to use to calculate the preferred width. If columns is set to zero, the preferred width will be whatever naturally results from the component implementation.

getUIClassID

public String getUIClassID()

Returns the name of the L&F class that renders this component.

Returns:

"PasswordFieldUI"

Overrides:

getUIClassID in class JTextField

See Also:

getUIClassID, getUI

getEchoChar

public char getEchoChar()

Returns the character to be used for echoing.

Returns:

the echo character

See Also:

setEchoChar, echoCharIsSet

setEchoChar

public void setEchoChar(char c)
