Exception Handling

The below example catches exception if you enter a value other than int

package Example1;
import java.util.InputMismatchException;
import java.util.Scanner;

public class ExceptionAgain {
 static Scanner scanobj=new Scanner(System.in);
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  System.out.println("how old are you");
  int age=checktheage();
  if(age!=0){
   System.out.println(" you are "+age+" old");
  }
 }

 public static int checktheage(){
  try{
   return scanobj.nextInt();
  }
  catch(InputMismatchException e){
   System.out.println("Do not enter whole number");
   return 0;
  }
 }
}

- We can add multiple catch block however the most appropriate exception should be mentioned first then the least excepted exception and then general exception.
- If we want to ignore an exception then catch the exception but do not do anything inside the block example is shown below

catch(InputMismatchException e){}
- Catching multiple exception in single catch is also possible.
catch(InputMismatchException | IOException e){} >>>Finally
