Thread: How to validate user input in a loop

Is there a method that allows me to check if the user entered anything other than an integer. For example I want the user only to enter an integer, I have this code.

 
			try 
			{
		         integerVariable = sc.nextInt();
 
			} 
			catch(InputMismatchException e)
			{
		     System.err.println("try again, wrong type");
			}
		}

That is only good for one time. How would I go about doing this in a loop say 5 times or something?

Yes I tried a while loop like this, but whenever I enter in a double for example. It will go into an infinite loop saying "try again wrong type"

int i=0;
while(i<3)
		{
		try 
			{
		         integerVariable = sc.nextInt();
                         i++;
			} 
			catch(InputMismatchException e)
			{
		        System.err.println("try again, wrong type");
			}
		}
		}

Right, but I thought that it would then eventually reach the top of the while loop and then go back into the try statement.

I ended up adding sc.next(); in the catch statement and now all is working well.
