QN040. Write a program which demonstrates the use of try, catch and finally statement with suitable example.

---

1. Objective

To create a program which demonstrates the use of try, catch and finally statement.

2. Theory

i. try

The try keyword is used to specify a block where we should place exception code. The try block must be followed by either catch or finally. It means we can't use try block alone.

ii. catch

The catch block is used to handle the exceptio. It must be preceded by try block which means we can't use catch block alone. It can be followed by finally block later.

iii. finally

The finnaly block is used to execute the important code of the program. It is executed whether an exception is handled or not.

3. Source Code

public class Qn040{
public static void main(String args[]){
try{
int data=25/0;
System.out.println(data);
}
catch(ArithmeticException e){System.out.println(e);}
finally{System.out.println("I am finally block I will always execute");}
System.out.println("rest of the code...");
}
}


4. Output

java.lang.ArithmeticException: /by zero
I am finnaly block I will always execute.
I am also executing

5. Conclusion

In this way, I would like to conclude that, we can use try, catch and finally statement to handle the different exception.
