   //Catch block
}
Java Exception

Catch Block

A catch block is used to handle an exception by declaring the type of exception you are trying to catch. It should be used after the try block.

Example

 public class ExceptionHandling{
    public static void main(String args[]){  
        try{  
            int a=1/0;  
        }
        catch(ArithmeticException ae){
            System.out.println(ae);
        } 
        finally{
            System.out.println("Always execute");  
        }
  	}  
}

Finally Block

A finally block of code always executes whether an exception is handled or not.

 

A finally block is also used for clean up processing e.g like closing connection, closing stream, closing a file, etc.
