title: Java - String Input Exception Handling
body: <p>I´m totally new to Java and I´m stuck. I have to create the game "guess the Number". I´m able to do the most parts but I´m don´t now how to handle the User Input if its a String.
  I want to be able to tell the User that the Input was not correct if he enters a String, and repeatedly ask for Input. It would be great if someone could help me here :)<br>
  Here is my Code: 
      </p>
  
  <pre><code>import java.util.Scanner;
  import java.util.Random;
  
  public class SWENGB_HW_2 {
  
  public static void main(String[] args) {
  
      System.out.println("Welcome to the guess the number game!\n");
      System.out.println("Please specify the configuration of the game:\n");
  
      Scanner input = new Scanner(System.in);
  
      System.out.println("Range start number (inclusively):");
      int startRange;
      startRange = input.nextInt();
  
      System.out.println("Range end (inclusively):");
      int endRange;
      endRange = input.nextInt();
  
      System.out.println("Maximum number of attemps:");
      int maxAttemp;
      maxAttemp = input.nextInt();
  
      System.out.println("Your Task is to guess the random number between "
              + startRange + " and " + endRange);
  
      Random randGenerator = new Random();
      int randNumber = randGenerator.nextInt((endRange - startRange) + 1)
              + startRange;
      int numberOfTries = 0;
  
      System.out
              .println("You may exit the game by typing; exit - you may now start to guess:");
      String exit;
      exit = input.nextLine();
  
  
      for (numberOfTries = 0; numberOfTries &lt;= maxAttemp - 1; numberOfTries++) {
  
          int guess;
          guess = input.nextInt();
  
  
  
          if (guess == randNumber) {
              System.out.println("Congratz - you have made it!!");
              System.out.println("Goodbye");
          } else if (guess &gt; randNumber) {
              System.out.println("The number is smaller");
          } else if (guess &lt; randNumber) {
              System.out.println("The number is higher");
          }
  
      }
      if (numberOfTries &gt;= maxAttemp) {
          System.out.println("You reached the max Number of attempts :-/");
      }
  
  }
  }
