Filled Blanks

The blanks can easily be filled with a little typing aided by copy and paste from other parts of the program.

import java.io.*;
import java.util.Scanner;

class AddDoubles
{
  public static void main (String[] args)
  {
    double first, second, sum;
    Scanner scan = new Scanner( System.in );
 
    // Read in the first double
    System.out.print("Enter the first double: ");
    first = scan.nextDouble();

    // Read in the second double
    System.out.print("Enter the second double: ");
    second = scan.nextDouble();

    // Compute the sum and write it out
    sum = first + second;
    System.out.print("Sum: " + sum );
  }
}

Here is a run of the program:

C:\temp>java AddDoubles
Enter the first double: 10.59
Enter the second double: 8.02
Sum: 18.61
