Need help with Client compiler

hey everyone, i know this is a noob question. but I have tried so many compiler codes and none of them work. and all I need is a compiler so I can compile a client so it’ll update the class files. can anyone help me? this is what I get everytime i go to compile.

'"C:\Program Files (x86)\Java\jdk1.8.0_66\bin"' is not recognized as an internal or external command, operable program or batch file. Press any key to continue . . .

this is the compiler i have set up as of now.

@echo off title compiler "C:\Program Files (x86)\Java\jdk1.8.0_66\bin" *.java pause

the whole C:\Program files (x86)\Java\jdk.1.8.0_66\bin" is my path and it is set. that’s why i don’t understand why it isn’t working. so close to chunking my computer out the window.

You gave the compiler a directory. It’s expecting a command, such as an .exe to run.

Where it says “\bin” add “\javac.exe”
