This project is a terminal local chat between two devices where one is hosting (by turning on hotspot) and other is client (by connecting to the turned on hotspot).
As the name suggests, it works locally between two devices (Later on this number will be increased), where one turns on hotspot, we call this device as server, other turns on WI-Fi and connects to the hotspot, we call this device as client, 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).
- In the server device, you must turn on hotspot.
- In the client device, you must connect to the server's hotspot, using WI-FI.
- 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 (Turn on hotspot).
Type 2 to be the client (Turn on wifi).
- To the device where hotspot is on, enter 1 and the terminal 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: [your hotspot ip], port: [choosen port]
Use the hotspot ip and choosen port in the other device doing:
- In the device where the WI-FI is connected, enter 2 and the terminal will show you:
>>> Enter the ip address:
- Enter the ip shown in the device where hotspot is on, 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.
