Java programming to realize the function of multi person chat room

This example shares the specific code of Java to realize multi person chat room for your reference. The specific contents are as follows

Program source code and running screenshot:

server. java

client. java

Test data I:

Screenshot of server program running:

Screenshot of client 1 program running:

Screenshot of client 2 program running:

From the test data, we can see that the program can realize multi person chat, and the effect and performance are OK. Moreover, when each client connects to the server, it will randomly generate a random number as its own flag, so as to avoid the poor communication effect caused by the unclear identification of each other during the call.

Test data II:

Screenshot of server operation:

Screenshot of client 1 program running:

Screenshot of client 2 program running:

Screenshot of client 3 program running:

Screenshot of client 4 program running:

Screenshot of client 5 program running:

Screenshot of client 6 program running:

Screenshot of client 7 program running:

Screenshot of client 8 program running:

Screenshot of client 9 program running:

Screenshot of client 10 program running:

In test 2, a total of 10 clients are connected to test the program stability. The program running results are stable and in line with the expected experimental results, which fully shows that the program has strong robustness.

The above is the whole content of this article. I hope it will be helpful to your study, and I hope you can support programming tips.
