Javac classpath / cp option not able to find the source file

I have a source file Example.java in the following location:
C:\Users\sushr\Desktop\Experimental Java code\tutorial
Result of dir command from tutorial directory:

Directory of C:\Users\sushr\Desktop\Experimental Java code\tutorial
10/10/2020  01:51 PM    <DIR>          .
10/10/2020  01:51 PM    <DIR>          ..
10/10/2020  01:51 PM               133 Example.java        <- This is the source file

I am trying to compile this file from location C:\ .
The command that I am running from the command prompt is the following:

C:\>javac -cp "C:\Users\sushr\Desktop\Experimental Java code\tutorial" Example.java

I am getting the following error:

error: file not found: Example.java
Usage: javac <options> <source files>

In macOS, I have noticed that using the "~/" to shortcut to home, it does not work. For example:

javac -cp .:~/algs4/algs4.jar MyFile.java

Instead, I had to use the full path to locate the .jar file in order to compile:

javac -cp .:/Users/username/algs4/algs4.jar MyFile.java

The classpath setting for javac is for finding other libraries and classes while compiling your .java files. It is not used for finding the .java files you specified as argument for the javac program. When you call javac Example.java and you are currently in the directory C:\, then it will look for a file C:\Example.java. It is most likely that the Example.java file will not be directly in the file system root C:\.

Either specify the .java files with an absolute path or adjust your working directory with cd "C:\Users\sushr\Desktop\Experimental Java code\tutorial\" to go in that directory and compile the files from that location.

If you specify the absolute path to your .java file you should be able to just compile it without the -cp flag like so:

C:>javac "C:\Users\sushr\Desktop\Experimental Java code\tutorial\Example.java"
