Basic Java

Im looking to write a java program, well two really, which provide the ability to transfer files using UDP protocol. This is for a school project so don't go on about UDP not being safe blabla, i know that.

So far I've came up with code enough to transfer strings and java objects from the client to the sever without any problems, however I cannot seem to be able to write code for transfering files. This can be any type of file.

I know that I am supposed to get a File object and then convert it to a byte array, but thats all I know so far.

Can anyone give me a hand on this? I can provide the code I have so far.

BTW: All answers on chrome seem either fishy or out of proportion to what I want.

 

I've never done it before, but couldn't you theoretically just load the file into a byte array as you say, then receive the same array on the server? If that doesn't work, then just make an ArrayList of bytes instead and send that to the server. An ArrayList is an object in Java terms so that should send no problem.

Also, if you're willing to experiment, figure out how to send an array of integers or maybe even just one integer. A byte is essentially the same thing just up to 128 and as low as -128.

 

Transferring a file would be the same as transferring binary data.
Create a DataOutputStream object, and just call the write method.

 

I've finished this now. Thanks anyway.
