BASIC ELEMENTS OF JAVA - Java Programming: From Problem Analysis to Program Design - page 58

Suppose the input is:
23 7

Next, consider the following statements:

feet = console.nextInt(); //Line 1

inches = console.nextInt(); //Line 2

The statement in Line 1 stores the number 23 into the variable feet . The statement in
Line 2 stores the number 7 into the variable inches . Notice that when these numbers are
entered at the keyboard, they are separated with a blank. In fact, they can be separated
with one or more blanks, lines, or even the tab character. (Note that we have numbered
the statements as Line 1 and Line 2, so that we can conveniently refer to a particular
statement and explain its meaning.)
The following Java program shows the effect of the preceding input statements:

// This program illustrates how input statements work.

import java.util.*;

public class Example2_16
{

static Scanner console = new Scanner(System.in);

public static void main(String[] args)
{

int feet;
int inches;

System.out.println("Enter two integers separated by spaces.");

feet = console.nextInt();
inches = console.nextInt();

System.out.println("feet = " + feet);
System.out.println("inches = " + inches);

}

}

Sample Run: (In this sample run, the user input is shaded.)
Enter two integers separated by spaces.
23 7
feet = 23
inches = 7
In the preceding program, notice the first line:

import java.util.*;
This line is required to use the class Scanner .
