JDK installed but no javap?
I have the JDK 10.0.2 installed, have the cmd opened in the folder of the class files of my program and try the command: javap Simulation.class .
I get the error that the command javap is not found. What do I do wrong?

Assuming you are on Windows, check in your environment variable PATH whether path to Java executables is set.
Ex. If you have installed Java on path,say, C:Program FilesJavajdk-10
Then you have to add C:Program FilesJavajdk-10bin to your PATH environment variable to be able to execute java commands from anywhere on command line.

On a sidenote, recommend you to move to Java 11 now that Java 10 is no longer supported. The above instructions would still remain same.

You must have your $JAVA_HOME/bin directory added to system PATH for javap command to be available without it's absolute path.
Alternatively you can call javap using the absolute path:
/usr/lib/../bin/javap Simulation.class

JAVA_HOME= "path of java installation on system"
export PATH = $JAVA_HOME/bin:$PATH
