Mainly in Java flush() is used to empty the buffer data between the server and the client.
Syntex for using this function is:

private DataOutputStream toServer;
toServer = new DataOutputStream(socket.getOutputStream());
double radius =5.0;
// Send the radius to the server
toServer.writeDouble(radius);
toServer.flush();

In java There will a buffer.when u write data to file or console it will initiall write to buffer then to file or console

Untill we use flush() method it will not be written into destination(file or console) from buffer

[Nicool]

For performance issue, first data is to be written into Buffer. When buffer get full then data is written to output (File,console etc.). When buffer is partially filled and you want to send it to output(file,console) then you need to call flush() method manually in order to write partially filled buffer to output(file,console).
