Hello all. I am new to Java and I am have some issues with some code I'm working on. I am having a problem with looping a while loop that contains a switch statement. Here is my code:

package hw4jenningsd;

import javax.swing.*;

public class HW4JenningsD {

public static class mathOps {

private int numOne;

private int numTwo;

private int numThreeOne;

private int numThreeTwo;

private String inputStringOne;

private String inputStringTwo;

public mathOps() {

numOne = 0;

numTwo = 0;

numThreeOne = 0;

numThreeTwo = 0;

} //end constructor

public void input() {

inputStringOne = JOptionPane.showInputDialog(null,"Enter your first "

+ "integer number");

numOne = Integer.parseInt(inputStringOne);

inputStringTwo = JOptionPane.showInputDialog(null,"Enter you second "

+ "integer number");

numTwo = Integer.parseInt(inputStringTwo);

}// end input

public void addition() {

numThreeOne = numOne + numTwo;

numThreeTwo = numOne + numTwo;

}// end addtion

public void subtraction() {

numThreeOne = numOne - numTwo;

numThreeTwo = numTwo - numOne;

}// end subtraction

public void multiplication() {

numThreeOne = numOne * numTwo;

numThreeTwo = numTwo * numOne;

}// end multiplication

public void division() {

numThreeOne = numOne / numTwo;

numThreeTwo = numTwo / numOne;

}// end division

public void modulo() {

numThreeOne = numOne % numTwo;

numThreeTwo = numTwo % numOne;

}// end modulo

public void displayResult() {

JOptionPane.showMessageDialog(null, "The result of your "

+ "calculations are " + numThreeOne + " and " +numThreeTwo+"\n and the two integers "

+ "you entered were "+numOne+ " and " +numTwo+ "\n and the type "

+ "of operation performed was "); //another problem. How can I code into this line the type of math operation was performed?

}// end displayResult

}// end class mathOps

public static void main(String[] args) {

String operationString;

int repeatOperation2;

int operationChoice;

mathOps mathOpsOne = new mathOps();

mathOpsOne.input();

JOptionPane.showMessageDialog(null,"Math operations Menu\nThe "

+ "purpose of this menu is to allow the user "

+ "to choose a\nmath operation to be performed.\n\n"

+ "1. +\n2. -\n3. *\n4. /\n5. %\n6. End the program.");

repeatOperation2 = 1;

operationString = JOptionPane.showInputDialog(null,"Press 1 to add,"

+ " 2 to subtract, 3 to multiply, 4 to divide, 5 for modulo, "

+ "or 6 to end the program");

operationChoice = Integer.parseInt(operationString);

while(repeatOperation2 == 1) {

switch(operationChoice) {

case 1: mathOpsOne.addition();

break;

case 2: mathOpsOne.subtraction();

break;

case 3: mathOpsOne.multiplication();

break;

case 4: mathOpsOne.division();

break;

case 5: mathOpsOne.modulo();

break;

case 6: JOptionPane.showMessageDialog(null,"Thanks for using "

+ "my program.");System.exit(0);

break;

default:JOptionPane.showInputDialog(null,"The selection is not"

+ " acceptable.\n Enter 0 to try again.");

break;

}// end switch operationChoice

mathOpsOne.displayResult();repeatOperation2 = 2;

while(repeatOperation2 == 2){

repeatOperation2 = Integer.parseInt(JOptionPane

.showInputDialog("Do you want to use the same "

+ "integers or a new set of integers" +

"\nPress [0] for new integers or [1] for same integers."));// one more problem. If the user chooses the same integers, how can I code it so that the user does not enter a new set of integers?

if(repeatOperation2 == 0) //this is where my problem is. I want the program to loop back to the math menu.

mathOpsOne.input();

else if(repeatOperation2 == 1){

repeatOperation2 = 1;

}

}

}// end while

JOptionPane.showMessageDialog(null,"Thanks for using "

+ "my program. ");System.exit(0);

}// end main

}// end program

Thanks for any assistance.
