☕ JAVA TRICK: Executing Source Files as Scripts

You know that you can use the'𝐣𝐚𝐯𝐚' command to launch a single source file without having to manually compile it first,

but did you know that you can use this capability to write full-on scripts in Java in just three simple steps?

First , add a shebang line to the source file that points at your '𝐣𝐚𝐯𝐚' executable, followed by '--𝐬𝐨𝐮𝐫𝐜𝐞' and the Java version the code was written for:

#!/𝑐/𝑃𝑟𝑜𝑔𝑟𝑎~1/𝐽𝑎𝑣𝑎/𝑗𝑑𝑘-17/𝑏𝑖𝑛/𝑗𝑎𝑣𝑎 --𝑠𝑜𝑢𝑟𝑐𝑒 17

Second, rename the file so it doesn't end with '.𝐣𝐚𝐯𝐚' extension - this is a great opportunity to gite it a good command-liney name.

Third make it executable with "𝐜𝐡𝐦𝐨𝐝 +𝐱".

There you go, script in Java!
