write a Java program to implement the GUI for a chat program. The program should include components attached to a form: a text field, a pop-up choice-group and up to 8 string items which will be messages entered by the user. Users should be presented with two commands, �Send� and �Exit�. Beneath the text field and user selection choice-group, there should always be no more than 8 string items, also identifying which user wrote which message. When a message is added to the group of messages, the text field should be erased ready for the next message. After 8 messages have been added to the group of messages, any additional messages are added to the end of the group and the first (oldest) message is removed. Another way to describe this is to display only the last 8 messages entered.
