Scanner class

[The Soul]

The Scanner class is a class that's able to parse data types when you input a value.

For example, I'm going to make a class that prints back what you've inputted.

In order to use the Scanner class, you're going to have to import the package like so:

Code:

import java.util.*;

Create our class:

Code:

public class Test {

Add our main method:

Code:

public static void main(String[] args) {

Now we'll have to create an object in order to use the class:

Code:

Scanner scan = new Scanner(System.in);

Declare a String:

Code:

String testing = "";

Print a line:

Code:

System.out.println("Type a word: ");

Make it so 'testing' is scanned:

Code:

testing = scan.next();

Print back the inputted word:

Code:

System.out.println("You entered: "+testing);

The full source code:

Code:

import java.util.*;
       public class Testing {
              public static void main(String[] args) {
                     Scanner scan = new Scanner(System.in);
                     String testing = "";
                     System.out.println("Type a word: ");
                     testing = scan.next();
                     System.out.println("You've entered: "+testing);
           }
    }

I recommend using a InputStreamReader or a BufferedReader rather than this, though.
