Exception handling in java

The Exception Handling in Java is one of the powerful mechanism to handle the runtime errors so that normal flow of the application can be maintained.

According to Oracle, there are three types of exceptions:

1. Checked Exception
2. Unchecked Exception
3. Error
4. Example -

   public class JavaExceptionExample{  
     public static void main(String args[]){  
      try{  
         //code that may raise exception  
         int data=100/0;  
      }catch(ArithmeticException e){System.out.println(e);}  
      //rest code of the program   
      System.out.println("rest of the code...");  
     }  
   }  

   Output-

   Exception in thread main java.lang.ArithmeticException:/ by zero
   rest of the code...

   Advantage of Exception Handling

   The core advantage of exception handling is to maintain the normal flow of the application. An exception normally disrupts the normal flow of the application that is why we use exception handling.
