控制台输入字符串之后回车,后台接收传来的字符串,代码如下:
import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class ReadLineDemo { public static void main(String[] args) { // System.in是获取键盘输入的值 // InputStreamReader将字节流转为字符流 转为BufferedReader BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); String line; try { //readLine()是阻塞方法,当键盘输入之后点击回车,否则就一直处于阻塞状态 while ((line = br.readLine()) != null) { System.out.println(line); } } catch (IOException e) { e.printStackTrace(); } } }
