Simple uses of the Scanner class

Here is a complete program using this class:

0021: import java.util.Scanner;                                 // SumProgNew.java
0022: public class SumProgNew 
0023: {
0024:    public static void main(String[] pArgs)
0025:    {
0026:       Scanner tScanner = new Scanner(System.in);
0027:       System.out.print("Type in your first number: ");
0028:       double tFirst = tScanner.nextDouble();
0029:       System.out.print("Type in your second number: ");
0030:       double tSecond = tScanner.nextDouble();
0031:       double tSum = tFirst + tSecond;
0032:       System.out.println("The sum of " + tFirst + 
0033:                          " and " + tSecond + " is " + tSum);
0034:    }
0035: }

This program produces a dialogue like the following:

0036: Type in your first number: 27
0037: Type in your second number: 42
0038: The sum of 27.0 and 42.0 is 69.0
