How to limit the textfield ?

Hi, I need a help. I should limit the number of typed letters. When that number pass over a value, the component (textfield) should not accept more typed letters. Example, suppose that the component just accept 5 letters. When the user type "ABCDEF", the component will just accept "ABCDE" and the letter "F" will not displayed.

Help me !!! thanks

Read the JTextField API. From there you will find a like "How to Use Text Fields" which will take you to the Swing tutorial on using text components. If you read the tutorial you will find out how to use:

a) a JFormattedTextField

b) a DocumentFilter

to achieve your desired goal.
