Java Tutorial : Java Exception handling (try-finally block) 
FinallyDemo.java
import java.util.Scanner;

public class FinallyDemo
{
    public static void main(String args[])
    {
        try
        {
            Scanner scanner = new Scanner(System.in);
            System.out.print("Enter the value of a : ");
            int a = scanner.nextInt();
            System.out.print("Enter the value of b : ");
            int b = scanner.nextInt();
            scanner.close();
            int c = a / b;
            System.out.println("c = " + c);
        }
        finally
        {
            System.out.println("finally block is always executed.");
        }
    }
}
Output
Enter the value of a : 10
Enter the value of b : 5
c = 2
finally block is always executed.

---------------------------------

Enter the value of a : 10
Enter the value of b : 0
finally block is always executed.
Exception in thread "main" java.lang.ArithmeticException: / by zero
