JAVA PROGRAM - no functions/methods

Display the menu shown below and get the users choice.

1. Addition

2. Subtraction (first operand larger)

3. Subtraction (first operand smaller)

4. Multiplication

5. Exit the program

If the user does not enter a valid choice, output "Valid choices are 1-5; please re-enter"

Get the lower and upper bound values the user wants to use for the math problems. Any integer values can be used. Upper bound must be greater than the lower bound. If the value entered for the upper bound is not greater than the lower bound, output an "upper bound must be > lower bound" and prompt for another value to be entered.

Display 5 problems of the user-requested type. For instance, if the user chooses option 1, your program should display an addition problem, using randomly-generated operands between the lower bound and the upper bound. Then it should get the users answer, check the answer and output message based on whether or not it is correct(if the answer was incorrect, the message should include the correct answer). Display problem/get answer/check answer steps should repeat a total of five times.

Repeat steps 1, 2, and 3 until the user chooses the exit option.

Keep track of the number of problems attempted and the number of problems correct. When the user exits,output the number of problems correct, the number of problems attempted, and the percentage of problems correct to 2 decimal places.

Use a while loop to repeat the menu display/get user choice action.

Use while loop for validation of the upper bound.

Use for loop to repeat the display problem/get answer/check answer steps

Do not use functions.

For random numbers, use

(int)(lowerBound + Math.random() * (upperBound lowerBound + 1))
