Programming in Java CSCI 1601 Section Assignment 4 NOTE: To create a random number you must declared the random object ex private Random randomNumber new Random Then create the number ex int number randomNumber.nextint(10%it generates a number between 0-9 number randomNumber nextint(10it generates a namber between 1 10 Computer-Assisted Iastruction: Part 1: Write a program using classes and methods to allow the user to pick a type of arithmetic problem to study. An option of I means addition problems only, 2 means subtraction problems only, 3 means multiplication problems only. 4 means division problems only and 5 means random mixture of all thse types. The use of computers in education is referrod to as computer- assisted instruction (CAI). Write a program that will help an elementary school student learn arithmetic operations. Use a Random object to produce two positive one- digit integers. The program should then prompt the user with a question, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the student's answer. If it's correct, display the message Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate method should be used to generate each new question. This method should be called once when the application begins execution and each time the user answers the question corectly Part 2: (Computer- Assisted Instruction: Reducing Student Fatigue) One problem in CAl environments is student fatigue. This can be reduced by varying the computer's responses to hold the student's attention, so that various comments are displayed for each answer as follows: Possible responses to a correct answer Very good Excellens Nice work! Keep up the good work Possibler No. Please try again. Wrong. Try once more. Dont give up! No. Keep trying Use random- number generation to choose a number from 1 to 4 that will be used to select one of the four appropriate responses to each cormrect or incormect answer. Use a switch or if statement to issue the responses. responses to an incorrect answer: Part 3: (Computer- Assisted Instruction: Monitoring Student Perfomance) More sophisticatod computer- assisted instruction systems monitor the student's performance over a period of time. Count the number of correct and incorrect responses typed by the student. Afler the student types 10 answers, your program should calculate the percentages that are correct. If the percentage is lower than 759, display-Please ask your teacher for extra help.", then reset the program so another student can try t lf the percentage is 75% or higher display "Congratulations, you are ready to go to the next level!", then reset the program so another student can try it
