Testing if it is an Int and if not ask again

[Alexander_003]

Hello guys ,

so this what I wanna do , I want tot read 4 integers. But after each of them te program has tot test if the entered value is really an integer if it isn't it should display a error message and it should ask enter it again en so on .

this is what I have :
it's a part of a bigger file .

thanks on beyond .

int counter=0;
        while(counter<4){
            System.out.print("Geef een getal tussen 1 en 8 in  :  ");
            if(!in.hasNextInt()){
                System.out.println(MESSAGE.ERRORGAME);
                System.out.print("Geef een getal tussen 1 en 8 in  :  ");
                
                            }

          else   {
            poging[counter]=in.nextInt();
            }
            
            
            counter ++ ;
        }

Write a separate method that takes a string to use as a prompt and returns the int that was input. This simplifies the logic: just call the method four times.

At the moment you are only printing the error message once if the user enters a non int. Is this what you intend to do?

for(int ndx = 0; ndx < 4; ndx++) {
    poging[ndx] = readInt("Geef een getal tussen 1 en 8 in  :  ");
}


// ... somewhere else

    /**
     * Displays a given prompt and returns the int value entered.
     * TODO: gives the user ??? chances to get it right
     * TODO: what should be returned if the user doesn't enter an int???
     */
private int readInt(String prompt) {
    // TODO
}
