java 向文件中写中文和读取乱码问题

String str="中国人民解放军";

FileOutputStream outStream = new FileOutputStream(saveFile);
outStream.write(str.getBytes("GBK"));
outStream.close();

读取

BufferedReader br=new BufferedReader(new InputStreamReader(new FileInputStream(path),"ISO-8859-1"));

char[] temp_char=new char[1024];

br.read(temp_char);
