File content as byte array ?

Question

I have the following code :
File file = new File("path/to/file");
And I want to get the content of "file" as a byte array, something like :
byte[] byteArray = file.getContentAsByteArray();
How do I achieve this ?
Cheers !

Answer 1

The following is also possible.
//import java.io.*;import java.nio.channels.*;import
java.nio.ByteBuffer;
java.io.File file = new File("input.txt");
FileInputStream stream = new FileInputStream(file);
java.nio.channels.FileChannel
channel=stream.getChannel();
java.nio.ByteBuffer buffer =
ByteBuffer.allocate((int)file.length());// if length
is larger than Integer.MAX_VALUE iteration must be
used
channel.read(buffer);
channel.close();
stream.close();
byte[] bytes = buffer.array();
// for(int j=0;j<bytes.length;j++)
System.out.println(Integer.toHexString(bytes[j]));
This will, of course, only work in 1.4, because of the java.nio packages.
