When using try/catch/finally, with error inputmismatch exception, How do I correctly implement a finally block, WITHOUT getting an error

Question

AND YES I have looked at simialr quesions and NO I cannot find an answer to my question...If you have a question about my question or code. PLEASE ASK.

do{
         try {
            System.out.print ("Volume of a cone... V = 1/3(3.14)r^2(h)");
            System.out.println ();
            System.out.print ("Input Radius: ");
            radius = keyBoard.nextDouble ();
            System.out.print ("Input Height: ");
            height = keyBoard.nextDouble ();
         //math
            volume = 0.333 * pie * radius * radius * height;
            System.out.printf ("Volume =   " + volume);
         }//end try
         catch (Exception Error){
            System.out.println ("You Entered the Wrong Data.");
         }
         finally {

            System.out.println ();

            System.out.print ("Do you want to try again?");
            System.out.println ();
            System.out.print ("Input '1' to go again OR any other key to End.: ");
            counter = keyBoard.nextInt ();
         }//end finally

      }while (counter == 1);

Answer 1

problem:

counter = keyBoard.nextInt ();

After you input a string to the nextDouble it will consume the newLine character by the nextInt() and will result to InputMismatchException because newLine is not an Int.

solution:

consume the newLine character in your catch block before asking for input from the user

sample:

         catch (Exception Error){
            System.out.println ("You Entered the Wrong Data.");
            keyBoard.nextLine();
         }

EDIT:

boolean tryAgain = false;
    do{
         try {

             if(tryAgain)
             {
                System.out.println ();

                System.out.print ("Do you want to try again?");
                System.out.println ();
                System.out.print ("Input '1' to go again OR any other key to End.: ");
                counter = keyBoard.nextInt ();
                tryAgain = false;
             }

            System.out.print ("Volume of a cone... V = 1/3(3.14)r^2(h)");
            System.out.println ();
            System.out.print ("Input Radius: ");
            radius = keyBoard.nextDouble ();
            System.out.print ("Input Height: ");
            height = keyBoard.nextDouble ();
         //math
            volume = 0.333 * pie * radius * radius * height;
            System.out.printf ("Volume =   " + volume);
            tryAgain = true;
         }//end try
         catch (Exception Error){
            System.out.println ("You Entered the Wrong Data.");
            keyBoard.nextLine();
            tryAgain = true;
         }

      }while (counter == 1);
