Exception Handling (try...catch...finally)

The try...catch block is mainly use to handle exceptions in java as shown below.

First block : try
Second block : catch
Third block (optional): finally

Source: TestException.java

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;


public class TestException {

    public static void main(String[] args) {
        try {
       
            Scanner scanner = new Scanner(new File("ccc"));
       
        } catch (FileNotFoundException exception) {

            exception.printStackTrace();
            System.out.println("Please contact sysadmin. 5111");

        } finally {
            //close any database or other resources, as this block will be executed irrespective of any exceptions or not in above 2 blocks
        }
   
        System.out.println("Thank you.");

    }

}


As the ccc file is not available the above program throws exception of FileNotFoundException type
