分享JAVA 文件追加续写问题
BufferedWriter读写文件的时候不能续写吗
File read = new File("e:\\text.txt");
File write = new File("e:\\text1.txt");
BufferedReader br = new BufferedReader(new FileReader(read));
BufferedWriter bw = new BufferedWriter(new FileWriter(write));
String con = br.readLine();
while (con != null) {
bw.write(con +"\r\n");
con = br.readLine();
}
br.close();
bw.close();
为什么不是每次把text中的内容追加到text1中，而是覆盖
一定要用FileOutputStream，append吗
File read = new File("e:\\text.txt");
File write = new File("e:\\text1.txt");
BufferedReader br = new BufferedReader(new FileReader(read));
BufferedWriter bw = new BufferedWriter(new FileWriter(write));
String con = br.readLine();
while (con != null) {
bw.write(con +"\r\n");
con = br.readLine();

br.close();

实在太感谢了，我的技术实在太不过关了
