How to rewrite it with JAVA?

Answer 1

If you are trying to do it in a way that is compatible with C++, then you'll need to write the bytes to the socket. You can do this by wrapping the socket's output stream with a DataOutputStream, then writing each value in order.
Remember that a C++ struct is just a convention of accessing a linear array of bytes, so the above is equivalent.
If you are just trying to send an Object's data over a socket (to another Java app), then you can wrap the socket's output stream with an ObjectOutputStream, then just write the object to it.
