Hailstone Lab

Make these objects work as described using the starter code on your drive:

1. The Set button:
   1. IF there is a number in the textField that is >0,
   • set number to the value in the textfield.
   2. otherwise
   • randomly choose a number from 1-100 and display it on label 1
   3. set count to 0
   4. display number on label 1
   5. display Iterations: 0 on label 2
2. The Next button:
• change number to half the number if it was even and 3X number + 1 if odd.
• display number on label 1
• add 1 to the count
• display count on label 2
3. Quit button: ends the program:
   • System.exit(0);

Top score:

• IF number is a 1,2 or 4, display a message in bright red that says HAILSTONE! to show that you've reached the infinite hailstone loop.
  • Remove the message when the quit or set button is clicked.
• If count is > 10, display a message in green that says LONG SEQUENCE.
  • Remove the message when the quit or set button is clicked.

Checking to see if there is any input:

String input = box.getText();         // get the text out of the text field named box
 if(input.length()>0){                // if there is something in the box
 number=Integer.parseInt(input);}     // turn it into an int
 else{                                //otherwise
 number =(int)(Math.random()*100)+1;} //generate a random number
