2.6
The solution to Self-Review Exercise 2.6 is as follows:
1
// Ex. 2.6: Product.java
2
// Calculate the product of three integers.
3
import
java.util.Scanner;
// program uses Scanner
4
5
public class
Product
6
{
7
public static void
main(String[] args)
8
{
9
// create Scanner to obtain input from command window
10
Scanner input =
new
Scanner(System.in);
11
12
int
x;
// first number input by user
13
int
y;
// second number input by user
14
int
z;
// third number input by user
15
int
result;
// product of numbers
16
17
System.out.print(
"Enter first integer: "
);
// prompt for input
18
x = input.nextInt();
// read first integer
19
20
System.out.print(
"Enter second integer: "
);
// prompt for input
21
y = input.nextInt();
// read second integer
22
23
System.out.print(
"Enter third integer: "
);
// prompt for input
24
z = input.nextInt();
// read third integer
25
26
result = x * y * z;
// calculate product of numbers
27
28
System.out.printf(
"Product is %d%n"
, result);
29
}
// end method main
30
}
// end class Product
Enter first integer:
10
Enter second integer:
20
Enter third integer:
30
Product is 6000
