Java: File to Hex?

Question

I have a file in Java

FileInputStream in = null;
try{    
in = new FileInputStream(\"C:\\\\pic.bmp\");
}catch{}

I want to convert pic.b

Answer 1

If you want to fiddle with the bytes yourself, get a FileChannel from the FileInputStream, and then allocate a ByteBuffer and then read all the content into it. ByteBuffer also has methods to deal with larger chunks of bytes, in the two different byte orders.
