java - Getting Keyboard Input

Question

How do I get simple keyboard input (an integer) from the user in the console in Java? I accomplished this using the java.io.* stuff, but it says it is deprecated.

How should I do it now?

Answer 1

You can use Scanner class

Import first :

import java.util.Scanner;

Then you use like this.

Scanner keyboard = new Scanner(System.in);
System.out.println("enter an integer");
int myint = keyboard.nextInt();

Side note : If you are using nextInt() with nextLine() you probably could have some trouble cause nextInt() does not read the last newline character of input and so nextLine() then is not gonna to be executed with desired behaviour.
