Scanner Class Example 1:
import java.util.Scanner; //Needed for the Scanner class
/**
* This program demonstrates the use of the Scanner class
*/
public class Scanner1 {
public static void main(String[] args) {
String name;
int hours;
double payRate;
double grossPay;
//creates a scanner object to read standard input
Scanner input = new Scanner(System.in);
//Get the user's name
System.out.print("Enter your name: ");
name = input.nextLine();
//Get the number of hours worked this week
//ASSUMES INTEGER INPUT
System.out.print("Enter the number of hours you've worked this week: ");

//Get the user's hourly pay rate
System.out.print("Enter your hourly pay rate: ");

//Calculate Gross Pay

//Display the resulting information
System.out.println("Hello, " + name);

Read Character Example 2:
import java.util.Scanner;
/**
* This programs shows how to take a single character as input
*/
public class ReadCharacter {
public static void main(String[] args) {
String input;
//Holds the input
char answer;
//Holds the converted input as a single character
//Creates a scanner object with standard input
Scanner keyboard = new Scanner(System.in);
//Ask the user a question
System.out.print("Is your name Eric (Y=yes, N=no)? ");

answer = input.charAt(0);
//Gets the first character from the input
