how to convert from switches to methods

So I have this homework assignment where I need to get my application from switches to using methods to give me the same result. I usually am good in this class, but right now I am completely lost. I won't throw everything at you, but just something to hopefully get me started.

Here is a piece of the code using switches:

Code:

---

                /* Get Type of Math problem from the user */
input = JOptionPane.showInputDialog(null,"Enter the type of Math Problem "
                + "you would like to solve: \n\n"
                                + "Addition = 1\n"
                                + "Subtraction = 2\n"
                                + "Multiplication = 3\n"
                                + "Division = 4\n"
                                + "Enter the number of your choice: ");

        problemType = Integer.parseInt(input);

              switch(problemType){
                        case ADDITION:
                                /* get random values */
                                mathVar1 = (int)(Math.random() * 100);
                                mathVar2 = (int)(Math.random() * 100);
                                /* solve problem */
                                mathAnswer = mathVar1 + mathVar2;
                                /* Get answer of Math problem from the user */
                                input = JOptionPane.showInputDialog(null,"Solve: \n" + mathVar1 +  " + "
+ mathVar2);
                                userAnswer = Integer.parseInt(input);
                                break;
                        case SUBTRACTION:
                                /* get random values */
                                mathVar1 = (int)(Math.random() * 100);
                                mathVar2 = (int)(Math.random() * 100);
                                /* solve problem */
                                mathAnswer = mathVar1 - mathVar2;
                                /* Get answer of Math problem from the user */
                                input = JOptionPane.showInputDialog(null,"Solve: \n" + mathVar1 +  " - "
+ mathVar2);
                                userAnswer = Integer.parseInt(input);
                                break;
                        case MULTIPLICATION:
                                /* get random values */
                                mathVar1 = (int)(Math.random() * 100);
                                mathVar2 = (int)(Math.random() * 100);
                                /* solve problem */
                                mathAnswer = mathVar1 * mathVar2;
                                /* Get answer of Math problem from the user */
                                input = JOptionPane.showInputDialog(null,"Solve: \n" + mathVar1 +  " * "
+ mathVar2);
                                userAnswer = Integer.parseInt(input);
                                break;
                        case DIVISION:
                                /* get random values */
                                mathVar1 = (int)(Math.random() * 100);
                                mathVar2 = (int)(Math.random() * 100);
                                /* solve problem */
                                mathAnswer = mathVar1 / mathVar2;
                                /* Get answer of Math problem from the user */
                                input = JOptionPane.showInputDialog(null,"Solve: \n" + mathVar1 +  " / "
+ mathVar2);
                                userAnswer = Math.round(Float.parseFloat(input));
                                break;

                }

I need to get this same result by using methods.

I can use these method signatures:

Code:

---

public static int readProblemType(){}
public static int getAddProblem(int randomValue1 int randomValue2){}
public static int getSubProblem(int randomValue1 int randomValue2){}
public static int getMultProblem(int randomValue1 int randomValue2){}
public static int getDivProblem(int randomValue1 int randomValue2){}
public static int readAnswer(){}

---

Looking at what I need to do, how would I use

Code:

---

public static int readProblemType(){}

---

method to read the problem type? Or where should I start?

can anyone help?

just move some of the code to methods:

Code:

---

          switch(problemType){
            case ADDITION:
                /* get random values */
                mathVar1 = readProblemType();
                mathVar2 = readProblemType();
                /* solve problem */
                mathAnswer = getAddProblem(mathVar1 ,mathVar2);
                /* Get answer of Math problem from the user */
...
 
      break;
 
...
public static int readProblemType()
{
  return (int)(Math.random() * 100);
}
 
public static int getAddProblem(int randomValue1 int randomValue2)
{
  return randomValue1 + randomValue2;
}

---

and so on...
