Information is required regarding .bat file

I have one java project. I have to RUN on .bat before running the project. I am unable to understand or read its working structure. As I open it in TextEditor, it shows text as below

@ECHO OFF

set bin=./bin
set classes=%bin%/cadel.jar;%bin%/clinkx.jar;%bin%/clink170b_ns.jar;%bin%/ns.jar
set main=org.itolab.morihit.cadel2.Cadel2
set rule=data/default

start /min "cadel" java -classpath %classes% %main% %rule%

It looks similar to me, but I cannot understand it completely.

How it is using "set" and why is it necessary to run my java project through bat file?

set is the way .bat files define environment variables - here, in order to set up the classpath, the main class, etc.

It is not strictly required to run a java project via a .bat file, but considering the length of the command line required to run it (java -classpath ... org.package.MainClass arg1 arg2 etc.), it is simply more convenient.

It is not mandatory. Set is used to define variables. It improves readibility, maintainance and reuse.
