Re-enter information question

[viperkevin]

Hi guys,

I'm using BlueJ, doing a small project for College.
The project involves getting the user to enter information, do some calculations inside Java and showing the results a number of ways.

My problem is this:
How do I code it so that incorrect information needs to be reentered?

For example- If the user enters a grade of 110, it must be between 0-100 so how do I make it go back to reentering?
(Awkward wording )

Here's my current code:

System.out.print("Critical Thinking grade: ");
opGrade=sc.nextInt();
if(opGrade<0 || opGrade >100)
{
System.out.println("Please reenter the number");
System.out.println();
System.out.print("Critical Thinking grade: ");
stuNumber=sc.nextInt();
}
Using this way works, except if the wrong number is entered again, it just skips to the next question.

Kelp?

Regarding your question, you need to use a loop for this. Look up using a while loop since that's what you'll need.

A loop.
I didn't even consider that!

Thank you!
