making a calculator. I need some help with my code....

Question

I was making a calculator, and I could not figure out how to show the results, go back to menu, and set up the sentinel. I cannot use the number variable for sentinel so I used char but it doesn't work.. I seriously need your help guys.

Scenario: You will develop a program that will help a child with math. The child will be able to select Addition, Subtraction, Multiplication,
or Division as well Exit the program. Once the program is exited the results (How many correct/incorrect for each type of math program) of the
session will be displayed. Once the child selects a type (Add, Sub, Mult, Div) the child will continue working with that type of problem until
choosing to exit back to main menu. The program will display the math problem, prompt for an answer. The program will notify the child if
they are correct or incorrect. If incorrect the correct answer should be displayed by the program.

This is my code so far

System.out.println("1. Addition");
System.out.println("");
System.out.println("2. Subtraction");
System.out.println("");
System.out.println("3. Multiplication");
System.out.println("");
System.out.println("4. Division");
System.out.println("");
System.out.println("Enter q to exit");
System.out.println("");
System.out.println("***************");
System.out.print("Enter your selection: ");
}
