初学Java,IO之使用转换流,读取键盘输入(四十三)

import java.io.*;public class KeyinTest {public static void main(String[] args) {BufferedReader br = null;try{//将system.in对象转换成Reader对象InputStreamReader reader = new InputStreamReader(System.in);//将普通Reader包装成Buffereaderbr = new BufferedReader(reader);String buffer = null;//采用循环方式一行一行的读取while((buffer = br.readLine()) != null){//如果读取的字符串为exit,程序退出if(buffer.equals("exit")){System.exit(1);}//打印读取的内容System.out.println("输入内容为:" + buffer);}}catch (IOException ioe){ioe.printStackTrace();}finally{try{br.close();}catch (IOException ioe){ioe.printStackTrace();}}}}
