Question

I need help in creating a Java Program; To calculate the chapter from which you solve the programming exercise, below are the requirements;
• Divide the integer number representing your student ID by 4, consider the remainder and increment it by 2. The result you obtain represents the chapter number, and it should be either 2, 3 , 5 or 6.

* Depending on the chapter number obtained above, consider the following rules in calculating the problem number to solve:

• If the chapter number is 2, divide your student ID by 23, consider the remainder and increment it by 1. The result you obtain represents the number of the programming exercise you will solve for online discussions, which should be from chapter 2.

• If the chapter number is 3, divide your student ID by 34, consider the remainder and increment it by 1. The result you obtain represents the number of the programming exercise you will solve for online discussions, which should be from chapter 3.

• If the chapter number is 4 (you need to go to chapter 6), divide your student ID by 38, consider the remainder and increment it by 1. The result you obtain represents the number of the programming exercise you will solve for online discussions, which should be from chapter 6.

• If the chapter number is 5, divide your student ID by 46, consider the remainder and increment it by 1. The result you obtain represents the number of the programming exercise you will solve for online discussions, which should be from chapter 5.

*After calculating the number of the chapter, and the number of the programming exercise to solve, ask the user to enter the page number where the specific problem is located in the textbook. Display the requirement for the programming exercise using the following format: "Please solve programming exercise … (include here the number of the exercise) from chapter … (include here the number of the chapter), from page … (include here the page number)."

Answer 1

Answer:

 public static void main(String[] args)

 {

   int studentnumber = 123456;

   int divisor = 0;

   int chapter = (studentnumber%4)+2;

   

   switch(chapter) {

     case 2:

      divisor = 23;

      break;

     case 3:  

      divisor = 34;

       break;

     case 4:

      divisor = 38;

       break;

     case 5:  

      divisor = 46;

       break;

   }

   

   int exercise = (studentnumber % divisor) + 1;

   

  System.out.printf("Studentnumber %d divided by 4 plus 2 is chapter %d.\n", studentnumber, chapter);        

  System.out.printf("Studentnumber %d divided by %d is exercise %d.", studentnumber, divisor, exercise);  

 }

Explanation:

Above is just a bit of code to get you started with the first part. Hope you can figure out the rest.
