This project is a terminal local chat between two devices connected to the same Wi-Fi network (alternativelly you can use hotspot-Wi-Fi).
As the name suggests, it works locally between two devices (Later on this number will be increased), connected to the same Wi-Fi, or one turns on hotspot, other turns on WI-Fi and connects to the hotspot, both run the jar file, follow the instructions, after all, they can chat together locally using terminal.
To make they communicate themselves, I used server socket, where after one device connect to the other, both sides waits for the received message and print it from a background Thread and while the background thread waits for the received message, the main thread is sending the message by using socket connections and streams does this conversion from Strings to byte arrays and the reverse work.
The String before converted to bytes and be sent, it's serialized to JSON and then converted to bytes and sent, who receives the JSON String only does the reverse work of who sends it (I'm about the codes, not persons).
To use of the terminal local chat, you must to:
- Have two devices (and terminal in them).
- Connect them to the same Wi-FI (or turn on hotspot in one device and connect to it from other device).
- Have a Java Envinronment.
- Download a release executable jar file (I recommend the latest). [Optionally you can clone the repository and compile it yourself]].
- Run the jar file by using:
java -jar terminal-local-chat_<version>_.jar
- The console will show you:
Enter your username/nickname:
Just enter an username.
Note
This user/nick name will be shown in the other device.
- The console will show you:
Type 1 to be the server.
Type 2 to be the client.
- Enter 1 in one of the devices, then the console will show you:
>>> Enter the port to listen:
- Just choose the port (1024-65535) and wait the other device to connect. The terminal will show you:
Serving in ip: [local ip], port: [choosen port]
Use the local ip and choosen port in the other device doing:
- In the other device, enter 2 and the console will show you:
>>> Enter the ip address:
- Enter the ip shown in the other device device, then the terminal will show you;
Enter the listened port:
- Enter the choosen port and voilà, they're connected to each other, you're able to send messages, just enter something and it will show you in the other device's terminal.
