To install Java, open Termux and execute the following command:

```pkg install wget && wget https://raw.githubusercontent.com/MasterDevX/java/master/installjava && bash installjava```

17+
> Eventually, run ```wget https://raw.githubusercontent.com/MasterDevX/java/master/installjava && bash installjava``` to install Java if you arleady have ```wget``` installed.
18+
19+
> Or just ```bash installjava``` if you have the script arleady downloaded for some reason.
20+
21+
When installed, run ```java -version``` to check, if it's correcty installed (i.e. if it throws command not found error, it's clearly not.)
22+

After that you can run Java using ```java``` command.
24+
25+
We also provide an uninstaller, but since I'm writing this while making that script, there's no way I can attach a command here, as I need a link for that. Anyway, look for ```uninstall_java.sh``` in repo's home.
