Multiplication

Program Plan:

Multiply.java:

• Import required packages.
• Declare the class “Multiply”.
• Create an object for “random()”.
• Declare the required variables.
• Define the main method.
  • Create an object for scanner class.
  • Declare the variable “guessVal”.
    • Call the method “Question()”.
    • Get the guess number from the user.
    • Check whether the “guessVal” is not equal to “-1”.
      • Call the method “Response()”.
    • Get the guess value from the user.
• Definition of method “Question()”.
  • Get the two random numbers between 0 and 10.
  • Multiply the two numbers.
  • Print the two numbers.
• Definition of method “printResponse()”.
  • Check the condition is “true”.
  • For correct guess, give the corresponding case option.
  • For incorrect guess, give the corresponding case option.
• Definition of method “Percentage()”.
  • Calculate and return the result.
• Definition of method “Response()”.
  • Increment the “iter++”.
  • Check whether the “guess” is not equal to “crtAns”
    • Call the method “printResponse()”.
    • Check whether “iter” is less than “10”.
      • Call the method “Question()”.
    • Check whether “iter” is greater than “10”.
      • Call the method “Percentage()”.
      • Check whether the returned value from the method “Percentage()” is less than “0.75”.
      • Assign the variables to “0”.
      • Call the method “Question()”.

SampleTest.java:

• Definition of class “SampleTest”.
• Definition of main method.
  • Create an object for “MultiplyVal” class.
  • Call the method “quiz()”.
