How do I make my println repeat itself?

[DrMadolite]

Hey, I've been making my first from-scratch program and I wonder about an If statement:

int bMonth;
// bMonth is what the user types as his birthday month in the console, from 1-12.

System.out.println("Please enter your birthday month, as a number from 1 to 12:");
bMonth = info.nextInt();

if (bMonth < 1 || bMonth > 12) {
     System.out.println("A year only has 12 months. Please enter your birthday month again:");
     bMonth = info.nextInt();

} else {
     System.out.println("Now enter the present month of this year:");
     bMonth = info.nextInt();
}

Ignoring unrelated flaws of this code, my question is this: How do I make it so that, the next time you type a value > 12 or < 1, it reruns the same if statement so that the same line pops up consistently. Do I need to make a separate method for it and how would that method look like?

Thanks.

You need to enclose those statements in a while(...) loop so that they keep repeating until the while loop's boolean expression is false. For more on these constructs, please check out The While Loop.

Ok, thanks. I'm familiar with the While loop but was unsure on its behavior. As I understand it now, a while loop just reruns itself constantly until it can get out of it's own circle, right?

Problem: It still just runs it once:

System.out.println("Now, please enter your birthday month (from 1-12):");
bMonth = info.nextInt();
		
while (bMonth > 12 || bMonth <= 0) {
     System.out.println("A year has 12 months. Please type your birthday month again:");
     bMonth = info.nextInt();
}

System.out.println("This is the next question in the program");

I know there's something I've not added here, but I'm just not sure what it is. Maybe I need to make a do while loop?

Your loop works OK for me. My code that I used:

import java.util.Scanner;

public class Foo001 {
   public static void main(String[] args) {
      Scanner info = new Scanner(System.in);
      System.out.println("Now, please enter your birthday month (from 1-12):");
      int bMonth = info.nextInt();
               
      while (bMonth > 12 || bMonth <= 0) {
           System.out.println("I'm sorry, but the year has 12 months, not more and definitely not 0. Please type your birthday month again:");
           bMonth = info.nextInt();
      }
       
      System.out.println("This is the next question in the program");
   }
}

A do-while loop could work well here as well.

Hmm, strange. I'll play a round with it some more. If it works for you, then I'm thinking that the value stored in bMonth gets screwed up earlier in the program in some way. In either case, thanks for the quick help.

Cheers.
