Java加载二进制文件 [英] Java loading binary files

问题描述

请告诉我最好/最快的方法：

Please show me the best/fast methods for:

1）将非常小的二进制文件加载到内存中。例如图标;

1) Loading very small binary files into memory. For example icons;

2）加载/读取大小为512Mb +的非常大的二进制文件。也许我必须使用内存映射IO？

2) Loading/reading very big binary files of size 512Mb+. Maybe i must use memory-mapped IO?

3）当你不想考虑大小/速度但是必须做的事情时你的共同选择：将所有字节读入记忆？

3) Your common choice when you do not want to think about size/speed but must do only thing: read all bytes into memory?

谢谢!!!

PS对不起，也许是微不足道的问题。请不要关闭它;）

P.S. Sorry for maybe trivial question. Please do not close it;)

P.S.2。 镜像 C＃的模拟问题;

推荐答案

对于内存映射文件，java有一个nio包：内存映射文件

For memory mapped files, java has a nio package: Memory Mapped Files

检查小文件的字节流类： Byte Stream

Check out byte stream class for small files:Byte Stream

查看更大文件的缓冲I / O：< a href =http://download.oracle.com/javase/tutorial/essential/io/buffers.html =nofollow>缓冲流

Check out buffered I/O for larger files: Buffered Stream
