Help me: loops in java

[silvia]

I have a very simple exercise. I am trying to call several methods from the main. I can call the method and the java input works but I can't get it to go back to the main after a valid selection has been made.
Can someone steer me in the right direction please?

Code:

class sampledata

{
  public static final
  void main (String[] argv)
	
  {
	
         System.out.println("I am going to ask you some questions. Please  answer using capital letters for any A,B,C choices. Thankyou.");
		
         System.out.println("Do you live in the ");
		
         options1();
         question2();
		
  }//end main

	
   static
   void options1()	
			
  {
	System.out.println("(A) Northern Hemisphere");
	System.out.println("(B) Southern Hemisphere");
	System.out.println("(C) neither of the above");	
		
	int count = 2;
	do
	{
                KeyboardReader kb = new KeyboardReader();
		
	   char choose;
	   choose = kb.getChar();
		
	   switch (choose)
	    {
		case 'A':
		System.out.println("Ahah, so it is Spring right now for you.");
		break;
				
		case 'B':
		System.out.println("Like me you are approaching Winter. I hope it is mild for you.");
		break;
				
		case 'C':
		System.out.println("Hmmm, surely you know what hemisphere you live in. Try another selection.");
		break;
											
		default:
		System.out.println("That was not a valid selection");	
		}
	}while (count>1);	
   }
	
    static 
    void question2()
       {
	System.out.println("Question 2 not yet prepared. Come back soon.");
       }
}

Thanks

use a while?

[Eranga]

Ya, use the while lop until your requirement is satisfying.

Code:

int count = 2;
	do
	{
                KeyboardReader kb = new KeyboardReader();
		
	   char choose;
	   choose = kb.getChar();
		
	   switch (choose)
	    {
		case 'A':
		System.out.println("Ahah, so it is Spring right now for you.");
		break;
				
		case 'B':
		System.out.println("Like me you are approaching Winter. I hope it is mild for you.");
		break;
				
		case 'C':
		System.out.println("Hmmm, surely you know what hemisphere you live in. Try another selection.");
		break;
											
		default:
		System.out.println("That was not a valid selection");	
		}
	}while (count>1);

i dunno why did u use da count variable, but from what i c it, of course u cant go back to the main, da loop will go on and on as long as the count are still bigger than 1

Code:

	}while (count>1);

u didnt put any changes to da variable count in ur program after da valid selection A or B or C, maybe after da System.out.print() statement, u should put some means to change da count value from 2 to 1 or less, so that it can escape da loop...

jst correct me if i got ur point wrong k
