Write a class called UsingScanner. This class has a main method. Remember to import class Scanner from library java.util. If you don't have this line you will not be able to use the class Scanner. what this program does: 1. ask user to enter an integer (see example below) 2. read the integer using a Scanner object 3. print "I read an integer: " followed with whatever integer was read (see examples below) 4. ask user to enter a double 5. read the double 6. print "I read a double: " followed with whatever double was read 7. ask user to enter a String 8. read the String 9. print "I read a String: " followed with whatever String was read How to write it 1. Import the Scanner class from the java.util package import java.util.Scanner; 2. Create only one Scanner object connected to System.in Scanner input = new Scanner(System.in); 3. Print "please enter a integer: " System.out.print("please enter a integer: "); 4. Declare a variable of type int int x; 5. Read an int from the user and assign it to the variable x = input.nextInt(); 6. Print "I read an integer: " + x System.out.println("I read an integer: " + x); 7. do the same for double and for String (use the same Scanner object for these) Consuming the extra newline There is a problem when you use the Scanner to read a new line just after reading a primitive type such as a double or an int. This issue is explained in section 3.10 of the book (page 45). It is called "the scanner bug" The following text is quoted from Gaddis 6e book: Keystrokes are stored in an area of memory that is sometimes called the keyboard buffer. Pressing the Enter key causes a newline character to be stored in the keyboard buffer. The Scanner methods that are designed to read primitive values, such as nextInt and nextDouble, will ignore the newline and return only the numeric value. The Scanner class's nextLine method will read the newline that is left over in the keyboard buffer, return it, and terminate without reading the intended input. Remove the newline from the keyboard buffer by calling the Scanner class's nextLine method, ignoring the return value. Examples (what the user typed is shown in boldface) % java UsingScanner please enter a integer: 123 I read an integer: 123 please enter a double: 123.654 I read a double: 123.654 please enter a String: hello world, how are you! I read a String: hello world, how are you! %
