How can I get the user input in Java?

Answer 1

One of the easiest methods is to use a Scanner object as pursues:

import java.util.Scanner;

Scanner reader = new Scanner(System.in); // Reading from System.in

System.out.println("Enter a number: ");

int n = reader.nextInt(); // Scans the next token of the input as an int.

//once finished

reader.close();
