java 通过IO控制台输入内容写入到文本当中

BufferedReader br1 = new BufferedReader(new InputStreamReader(System.in));

BufferedWriter bw1 = new BufferedWriter(new FileWriter("测试A.dat",true));

System.out.println("请输入内容 ,输入exit结束：");

String line = null;

while(true) {

line=br1.readLine();

if(line.equalsIgnoreCase("exit")) {

break;

}

bw1.write(line);

bw1.newLine();

bw1.flush();

}

bw1.close();

System.out.println("输入结束！！！");

BufferedReader br3 = new BufferedReader(new FileReader("测试A.dat"));

String line3=null;

while((line3=br3.readLine())!=null) {

System.out.println(line3);

}

br3.close();
