（java）在文件little endian中编写 [英] (java) Writing in file little endian

问题描述

我正在尝试编写TIFF IFD，我正在寻找一种简单的方法来执行以下操作（此代码显然是错误的，但它可以解决我想要的问题）：

I'm trying to write TIFF IFDs, and I'm looking for a simple way to do the following (this code obviously is wrong but it gets the idea across of what I want):

out.writeChar(12) (bytes 0-1)
out.writeChar(259) (bytes 2-3)
out.writeChar(3) (bytes 4-5)
out.writeInt(1) (bytes 6-9)
out.writeInt(1) (bytes 10-13)

会写：

0c00 0301 0300 0100 0000 0100 0000

0c00 0301 0300 0100 0000 0100 0000

我知道如何让写入方法占用正确的字节数（writeInt，writeChar等），但我不知道如何让它以小端写入。有人知道吗？

I know how to get the writing method to take up the correct number of bytes (writeInt, writeChar, etc) but I don't know how to get it to write in little endian. Anyone know?

推荐答案

也许你应该尝试这样的事情：

Maybe you should try something like this:

ByteBuffer buffer = ByteBuffer.allocate(1000); 
buffer.order(ByteOrder.LITTLE_ENDIAN);         
buffer.putChar((char) 12);                     
buffer.putChar((char) 259);                    
buffer.putChar((char) 3);                      
buffer.putInt(1);                              
buffer.putInt(1);                              
byte[] bytes = buffer.array();
