1. Just start the game the background color of JFram window is magenta. The first line of the window contains JLabel messages "I have a number between 1 and 1000.”. The 2nd line contain “Can you guess my number? Enter your first Guess:." JLabel message. A JText filed should be at the beginning of third line and follow by a “Guess result appears here." JLabel, and a “New Game” Jbutton. 2. As each guess is input, the background color should change to either red or orange. Red indicates that the user is getting closer (“warmer”) to the answer and orange indicates that the user is getting farther (“colder”) to the answer. At this stage the number guessed should be displayed at the top of the window. The second line should still display “Can you guess my number? Please enter your first guess.” JLabel message. A JText filed should be at the beginning of third line and follow by a “Too high..” or “To low ..” JLabel message, and a “New Game” Jbutton. 3. When the number is guessed the background will be in green color. The first line of the window displays "After # trials you get the number # correct." JLabel message. The 2nd line displays "You are great! Try again? Click "New Game" button.”. :." A JText filed should be at the beginning of third line and follow by a “Correct." JLabel, and a “New Game” Jbutton. 4. When the “New Game” Jbutton clicked the window will be in yellow color. The first line of the window contains JLabel messages "I have a number between 1 and 1000.”. The 2nd line contain “Can you guess my number? Enter your first Guess:." JLabel message. A JText filed should be at the beginning of third line and follow by a “Guess result appears here." JLabel, and a “New Game” Jbutton. Create a driver to display the capability of the program designed.

???? Even I entered 1 as a first guess, the title would still too high. After the first guess, the color didnt change (still magenta) to either orange or red. The program stop at the third guess. I'm not sure if it change to green. Does this program contains include this statement if the answer is correct? I want to display message for each guess ex: Please enter your 3 ... 4 .. after you guess wrong?
