Not sure what exactly this sentence mean: "Locate the classpath.txt file for the MATLAB installation?"

I am trying to call java from matlab using instructions from here:

https://www.mathworks.com/matlabcentral/answers/99993-how-do-i-call-a-simple-hello-world-java-program-in-matlab

In the 2nd step I need to do: "Locate the classpath.txt file for the MATLAB installation?"

What does this exactly mean?

I already installed matlab.

Read on to the next sentence:

"The location of this file can be found by typing the following command in MATLAB command window:

which classpath.txt"

Thanks Ken but I am not asking how. My question is that I already installed matlab and what does it mean to "Locate the classpath.txt file for the MATLAB installation". What does MATLAB installation mean? Does that mean the location that matlab is installed? but which folder? The isntalled folder of matlab has many subfolders.
