Can't take User input with DataInputStream!!!

Question

public class DataInputStrm
     public static void main( String[] args ) {
          DataInputStream dIpStream = new DataInputStream( System.in );
             try {
               System.out.println( "Enter an integer" );
               int anInteger = dIpStream.readInt();
               // does not work
               System.out.println( "You have entered " + anInteger );
          catch( java.io.IOException e ) {
               e.printStackTrace();
     } // end of main
} // end of class DataInputStrm/** Problems:
1. If an one digit integer is entered( 2, 3 etc ), it is waiting for another!
     Does not happen for an integer with more than one digit.
2. Displays garbage when the integer value is output.
Please help immediately!

Answer 1

DataInputStream/DataOutputStream provide a way of reading and
writing complex objects in a way that works on all sorts of different
computers.
What you probably want is a Scanner. These things are designed
to read relatively simple data only (numbers, strings, lines, boolean
values etc) from just about any source (anything Readable).
Here's your example, but using a Scanner:import java.util.Scanner;
public class ScanEg
    public static void main( String[] args ) {
        Scanner in = new Scanner(System.in);
        System.out.println( "Enter an integer" );
        int anInteger = in.nextInt();
            // but what if it's not an integer...
        System.out.println( "You have entered " + anInteger );
}Works fine, but you might want to consult the documentation to
find out what happens if the user doesn't enter a number, or if
there's an i/o error. The API documentation is here:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Scanner.html
Scanner is discussed in the tutorial here:
