谢谢老师，老师辛苦了

您看看这个该怎么写呢？

追答

                PrintWriter out;
try {
out = new PrintWriter("D:\\1.txt");
} catch (FileNotFoundException e) {
e.printStackTrace();
return;
}

out.print(ss);
out.println();

out.close();

加一个try-catch吧

Answer 2

public static void writeFile(String content, String file) {
try {
File f = new File(file).getParentFile();
if (!f.exists()) {
f.mkdirs();
}
FileOutputStream fos = new FileOutputStream(file);
Writer out = new OutputStreamWriter(fos, "UTF-8");
out.flush();
out.write(content);
out.close();
} catch (IOException ex) {
throw new RuntimeException(ex);
}
log.debug("Write File:" + file);
}
