Exception Handling with and without using try catch block

Advertisement
In this tutorial it demonstrate the way of using exception handling. One using throws and other using try catch block

Description:

Without using try catch block. If you do not want to explicitly make try catch block then to you program write throws Exception to your method where Exception handling is required 

Code: 

class exceptionHandle {

      public static void main(String args[]) throws Exception {

            int a = 5;

            int b = a / 0;

            System.out.println(b);

      }

}

Output: 

Exception in thread "main" java.lang.ArithmeticException: / by zero

at exceptionHandle.main(exceptionHandle.java:7) 

Now the other way to use Exception Handling is by using try catch block shown in following code sample:

 class exceptionHandle {

      public static void main(String[] args) {

            try {

                  int a = 5;

                  int b = a / 0;

                  System.out.println(b);

            }

catch (Exception e) {

            System.out.println(e);

            }

      }

}

Output: 

java.lang.ArithmeticException: / by zero
