Updating text file in java
The reason is that the percent format used by the display formatter automatically displays the text as 100 times the value, so the corresponding editor formatter must display the text at the same value.Additional Unicode line terminators may be recognized in future releases.
Using the formatters that Swing provides, you can set up formatted text fields to type dates and numbers in localized formats.
Another alternative or adjunct to using a formatted text field is installing an input verifier on the field.
A component's input verifier is called when the component nearly loses the keyboard focus.
Another kind of formatter enables you to use a character mask to specify the set of characters that can be typed at each position in the field.
For example, you can specify a mask for typing phone numbers in a particular format, such as (XX) X-XX-XX-XX-XX.
