The error "javac is not recognized on windows 10" commonly occurs with beginners or Java programming. The javac is a command used to compile the java programs; it invokes the javac.exe application in the bin directory of JDK.

Whenever the error "javac is not recognized" occurs, the JVM cannot find the file javac.exe. Either the file has been deleted, or the Environment variable is not set for the JDK.

javac can be found in the C:\Program Files\Java\jdk-17.0.2\bin directory.

If JVM cannot find the javac file, it will throw the "javac is not recognized on windows 10". See example:
