java学习笔记-IO向文件末尾追加内容

最近被问到文件追加内容，今天百度学习了相关资料，现在记录一下：
三种方式：字节输出流，字符输出流，随机访问文件流public static void appendFile(){
//方法一
try {
FileOutputStream out = new FileOutputStream("G:/file.txt", true);
String content = "-- append the method one !---";
out.write(content.getBytes());
out.close();
} catch (IOException e) {
e.printStackTrace();
}

//方法二
try {
FileWriter writer = new FileWriter("G:/file.txt", true);
String content = "-- append the method two !--";
writer.write(content);
writer.close();
} catch (IOException e) {
e.printStackTrace();
}

//方法三
try {
RandomAccessFile accessFile = new RandomAccessFile("G:/file.txt", "rw");
//获取文件长度
long length = accessFile.length();
//设置文件指针移动到文件末尾
accessFile.seek(length);
String content = "-- append the method three !--";
accessFile.write(content.getBytes());
accessFile.close();
} catch (IOException e) {
e.printStackTrace();
}

}
