Java 使用 BufferedWriter 将键盘输入写入文本文件

import java.io.*;

public class WriteToFile { public static void main(String[] args) { BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); BufferedWriter bw = null; try { File file = new File('output.txt'); bw = new BufferedWriter(new FileWriter(file)); System.out.println('请输入要写入文件的内容（输入exit结束）：'); String line = ''; while (!line.equals('exit')) { line = br.readLine(); bw.write(line); bw.newLine(); } System.out.println('内容已写入文件output.txt'); } catch (IOException e) { e.printStackTrace(); } finally { try { if (bw != null) { bw.close(); } if (br != null) { br.close(); } } catch (IOException e) { e.printStackTrace(); } } }
