HI All

i have a text file which is of size 6 mb,which i need to send across net.
so i want to split this file in 2 files, which is of 3mb each.

can any one suggest me How can i split a file in java when its size is more than say 6mb.

I guess you can manually do it by getting the size of the file through the length() method on the file and you can split it accordingly.

length() method returns a long value - FYI. [as per Java 2]

i m not sure which version of JDK you use and the support the higher versions have (Tiger, Mustang). Just check the respective JavaDocs for the same.

Do you know how to read and write files? If not, the Java Tutorial IO chapter is a good place to start.
I'm curious, why are you splitting the file? There's no arbitrary limit to the length of a stream. Do you have a receiving process that will reassemble the file?

i need to split file because , iwant to send these files over queue.
but my queue limit is 4MB, so i cant send file of size more than 4mb to a queue. if my file size is more than 4mb , i need to split it and send over queue

OK. So have you read the tutorial? Can you read/write files? What specifically do you need a hand with?
