Need help with loop!!

[chrisLU5]

Hi my tutor set me a task to complete, basically i need my program here to loop back to the optionSelected part of my code, i know how to write to it counts the vote ect, i just need to know how to loop the whole sequence so it doesn't just close when a user votes for a team....

import Barnfield.Dialogs;

class VoteSystem {
	public static void main (String args[]) {
		int optionSelected;
		double total;
		
		Vote question1 = new Vote();
		question1.setQuestionNumber(1);
		question1.setQuestion("Arsenal");
		
		Vote question2 = new Vote();
		question2.setQuestionNumber(2);
		question2.setQuestion("Bayern Munich");
		
		Vote question3 = new Vote();
		question3.setQuestionNumber(3);
		question3.setQuestion("Chelsea");
		
		Vote question4 = new Vote();
		question4.setQuestionNumber(4);
		question4.setQuestion("Fenebarche");
		
		optionSelected = Dialogs.integerInput("Select: \n 1: View \n 2: Vote \n 3:Exit");
		
		if (optionSelected > 3){
			Dialogs.errorMessage("You entered a wrong number");
		}
		if (optionSelected == 1){
			Dialogs.outputMessage("The current score is ");
			}
		if (optionSelected == 2){
			optionSelected = Dialogs.integerInput("Enter a number for the following answers: \n 1: Arsenal \n 2: Bayern Munich \n 3: Chelsea \n 4: Fenebarche");
		if (optionSelected == 1)
			Dialogs.outputMessage("You Voted For :" + " " + question1.getQuestion());
		if (optionSelected == 2)
			Dialogs.outputMessage("You Voted For :" + " " + question2.getQuestion());
		if (optionSelected == 3)
			Dialogs.outputMessage("You Voted For :" + " " + question3.getQuestion());
			
		if (optionSelected == 4)
			Dialogs.outputMessage("You Voted For :" + " " + question4.getQuestion());
		}
		if (optionSelected > 4){
			Dialogs.errorMessage("You entered a wrong number");
		}
		if (optionSelected == 3){
			Dialogs.outputMessage("Program Closing");
		}

		System.exit(0);
	}

		
		}

Many Thanks Chris

Do you understand the three types of loops? Do ... While, while, and for.

Do while ensures that the loop body is performed at least once

do{
  Something fun
}while(condition is true);

While is good for looping x times, where x is unknown

while(condition is true){
  Do something less fun
}

A for loop is good for doing something x times, where x is known

for(int i = 0; condition is true; i++){
  Do something more fun
}

The oracle tutorials have more detailed explanations of all three. Which loop you need is upmto what you want, all three loops can function the same way.

I dont understand them fully, i just need a starting point, i don't understand that when option 2 is selected and the user votes for a team how to return back to the main menu to select option 1 to view the score?
