java file compilation using cmd( javac )

Question

Recently my teacher demonstrated how to compile ".Java" file using cmd. But when I tried to compile using "javac Hello.java"(name I kept for the file btw) I got "javac is not recognized as Internal or external command".Then I saw YouTube videos and added path in Environment variable as said I YouTube, but still I got the same error. Later I found there is no "javac.exe" file inside bin. I have installed Java version "18.8.0_301".

Answer 1

Its all explained in detail on the official site. After installing JDK you need to add <jdkPath>/bin to the PATH environment variable, that will let you type javac in cmd without specifying the absolute path to it. Make sure to restart cmd after so it reads the new PATH variable.
