Question

The game must be done in java in Netbeans

1. Write a Guessing Game. In the game, the user will guess a number. a. In the StartGui, the use needs to choose a difficulty level: Easy or Difficult. If easy level is selected, the user will guess between 1 and 10. If difficult level is selected, the user will guess 1 and 100. Then the user will click Start button and go to the GamePage. b. In the GamPage, the user will enter his/her guess in a textfield. The interface will give a hint to the user that the user needs to guess a higher or lower number and allow the user to enter a new guess. The user has a maximum of ten tries. You need to display number of tries left. There is a button "Give UP". If tries limit (10 times, ie the u each number), the answer will show up in a new Window (a new swingGUI frame). If the guess is correct, the new window will tell the player that he/she is right. The player can choose to play again from the StartGUI
