java-获取控制台输入（传统）

public static void main(String[] args) {BufferedReader bufferedReader=new BufferedReader(new InputStreamReader(System.in));try {String string=bufferedReader.readLine();System.out.println("hhhh"+string);} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}

传统;以字符读入。跟读文件一样。

import java.util.Scanner;public class Main {    public static void main(String[] args) {        Scanner in = new Scanner(System.in);        while (in.hasNextInt()) {            int a = in.nextInt();            int b = in.nextInt();

//String c =in.nextLine();

            System.out.println(a + b);        }    }}
