Question
You will be creating only a driver class in netbeans/java. As part of writing this Rock-Paper-Scissors program, be sure to include a message to the user explaining the program. Also, there is one additional element required in this program. You must validate the data entered by the user to ensure that his/her choice is one of the three allowed options. If bad data is entered, the program must provide feedback about the error and again prompt for and read in the user’s choice. make the program randomly generate rock paper or scissors(1,2, or 3). include clear comments throughout the program that explain what functionality the various lines/small sections of code/methods are as related to the execution of the program.
