The java code reads the code of the port.properties file

Recently, a java socket service [

A socket server that can accept the information sent, and then broadcast it

】

You need to use a java class to read the content of another properties file, and make a note here for future viewing!

The contents of the port.properties file are as follows

port=9999

The Server.java class is as follows, loaded. . . . . . The port number in port.properties is 9999
