Question

Write a Java program that plays "guess the number".

The program will generate a random number from 1 through 10.

The user enters a number in the textfield and clicks the "Check

Answer" button.

The computer will tell the user if the guess is too high or too low.

If the guess is too high or too low, the user will guess another number

and click the "Check Answer" button.

The user will guess numbers until the message "You guessed the

number!" is displayed.

Set the frame size to 300, 125

Output should look like this: http://imgur.com/R05k9Gl

I started it up, but my month off for winter break has really taken its toll on what I can remember, and I can't get it right.
