Write a complete program that calculates and prints the product of three integers.

```
// Product.java
// Calculate the product of three integers.
import java.util.Scanner; // program uses Scanner

public class Product {
public static void main(String[] args) {
// create Scanner to obtain input from command window
Scanner input = new Scanner(System.in);

System.out.print("Enter first integer: "); // prompt for input
int x = input.nextInt(); // read first integer

System.out.print("Enter second integer: "); // prompt for input
int y = input.nextInt(); // read second integer

System.out.print("Enter third integer: "); // prompt for input
int z = input.nextInt(); // read third integer

int result = x * y * z; // calculate product of numbers

System.out.printf("Product is %d%n", result);
} // end method main
} // end class Product
```

Enter first integer: 10
Enter second integer: 20
Enter third integer: 30
Product is 6000
