Thread: Guess Number (Frame & btnHandler)!!!! HELP

I can get GUI run as i want to... Can any1 help me to look at it!

Write a application that plays “guess the number” as follows: Your application chooses the number to be guessed by selecting an integer at random in the range 1-100. The application then displays the following in a label:

I have a number between 1 and 100. Can you guess my number?

A JTextField should be used to input the guess. As each guess is input, a hint message will be output to tell the user if the number enters is too low or too high.

A JButton should be provided to allow the user to play the game again. When the JButton is clicked, a new random number should be generated.

(Size of the window is width: 280 pixels and height: 150 pixels)

The problem seems to be that you're adding your ButtonHandler to a JTextField.
