Answer 1

There are few different ways:

public class ConsoleReadingDemo {
public static void main(String[] args) {
// ====
BufferedReader reader =
new BufferedReader(new InputStreamReader(System.in));
System.out.print("Please enter user name : ");
String username = null;
try {
username = reader.readLine();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("You entered : " + username);

// ===== In Java 5, Java.util.Scanner is used for this purpose.
Scanner in = new Scanner(System.in);
System.out.print("Please enter user name : ");
username = in.nextLine();
System.out.println("You entered : " + username);

// ====== Java 6
Console console = System.console();
username = console.readLine("Please enter user name : ");
System.out.println("You entered : " + username);
}
}

Answer 2

import java.util.Scanner;
class ....{
...main(String args[]){

Scanner stdin = new Scanner(System.in);
stdin.nextInt();

you import the scanner class
you make a new Scanner object here I called it stdin (standard input).Then you cal the method you want here I asked for an integer.You may also use stdin.nextDouble() ,or for strings
