Don't have time to say much right now, but go take a look at Scanner. |

I think that the Scanner class is out-of-date, we now use this: import java.io.*; public class <class name> { public static void main (String args[]) throws IOException { BufferedReader br = new BufferedReader (new InputStreamReader (System.in)); System.out.print ("Enter text: "); String text = br.readLine(); //code to make use of the variable "text" } } |

Two things: 1. Scanner is not out-of-date; depending on application you may use either the method you list or Scanner or some combination or variation. 2. You resurrected a thread that's almost 7 years old. Please try to post only in recent threads. |

import java.util.Scanner; /*you must use this import statement to use the scanner class*/ Scanner scan = new Scanner(System.in); /*this is the syntax of how to instantiate a new scanner. you can substitute the "scan" for the variable of your choosing*/ kb.nextLine(); //reads in a String from the keyboard kb.nextInt(); //reads in an int (integer) from the keyboard kn.nextDouble(); //reads in a double from the keyboard kb.nextBoolean(); //reads in a boolean from the keyboard kb.nextLong(); //reads in a long from the keyboard |
