socket write error ..... everyone help, thank you

Maybe the connection is broken.

LZ is not so good when naming variables, InputStream and OutputStream are themselves class names
 
 Try to change the variable name first.
 
 The User object implements the serial interface.

The connection is not broken, the User object has been serialized
