Help with assignment.

Heya guys I'm new around here. I would like for lil help with my assignment .
What I want to to is when user inputs the int for price ( tehPrice ) I want it to make sure it is int , and also make a
loop which requires the input to be int
and if it isn't then it should go back and asks for input again. I tried some things with do and while ( setting boolean called correct) but then i had some
error saying not initialized .
Cheers.

Code:

---

public void newArtItem() throws InputMismatchException
    {
        String tehName; int tehPrice; String tehFilename;
        scannie = new Scanner(System.in);
        System.out.print("Enter the name of the Art Item : ");
        tehName=scannie.next();

        System.out.print("What file does it corresponds to  ?  : ");
        tehFilename=scannie.next();
        System.out.println("Enter it's price : ");
        try
        {
            tehPrice=scannie.nextInt();
         
         

        }

        catch(InputMismatchException zed)
        {
          System.out.println("Not valid number");
        }

       
        artItem = new ArtItem(tehName,tehFilename,tehPrice);
        artItems.add(artItem);

    }

For a local variable you must give a initialization value before you can use it. For example for your loop condition check you can give it an initial value like:

Code:

---

boolean correct = false;

while (!correct) {
...
}

Hello and welcome to java-forums.org!

I think that you may be over-complicating your solution a little since Scanner can check what type of input is available with its hasNextXXX() methods. So exceptions may not be necessary to solve this. One possible solution in "pseudo-code" is:

Code:

---


Ask for int input
loop: while scan's next input is NOT an int
  use the Scanner to get the next line and do nothing with it.
  Tell that they again need to enter an int
end of loop

get int from Scanner and use it.
