可以指定編碼如：utf-8來寫入和讀取文件。如果文件編碼未知，可以通過該方法先得到文件的編碼后再指定正確的編碼來讀取，否則會出現(xiàn)文件亂碼問題。
如何識別文件編碼請參考：java自動根據(jù)文件內(nèi)容的編碼來讀取避免亂碼

file.delete();
file.createNewFile();

new FileOutputStream(file), encoding));
writer.write(content);
writer.close();
}
public static String read(String path, String encoding) throws IOException {
String content = "";
File file = new File(path);
BufferedReader reader = new BufferedReader(new InputStreamReader(
new FileInputStream(file), encoding));
String line = null;
while ((line = reader.readLine()) != null) {
content += line + "\n";
}
reader.close();
return content;
}
public static void main(String[] args) throws IOException {
String content = "中文內(nèi)容";
String path = "c:/test.txt";
String encoding = "utf-8";
ReadWriteFileWithEncode.write(path, content, encoding);
System.out.println(ReadWriteFileWithEncode.read(path, encoding));
}
}
