Beispiel für die Verwendung von Java-Eingabestream-Scanner/BufferedReader

import java.util.Scanner;

public class Test {
    @SuppressWarnings("resource")
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println(scanner.next());
    }
}

import java.io.*;

public class Test {

    public static void main(String[] args) {
        try {
            BufferedReader br = new BufferedReader(new InputStreamReader(
                    System.in));
            System.out.println(br.readLine());
        } catch (IOException e) {

        }
    }
}
