I believe the correct answer is the one that refers to an exception trace being seen from the jdeps command.

The jdeps -summary TestClass.java doesn't work, as it doesn't seem to work with a java (text) file. I tried
jdeps -summary TestClass.java
and received an exception stack trace:
Exception in thread "main" com.sun.tools.classfile.Dependencies$ClassFileError

Then I tried with
jdeps -summary TestClass.class
and got the following result:
TestClass.class -> java.base
TestClass.class -> java.desktop
TestClass.class -> java.sql

You are right. That should be just TestClass and not TestClass.java
Fixed.
thank you for your feedback!

Actually, no. Just saying
jdeps -summary TestClass
doesn't work, either. Below is what I experience:

C:\code\java\ocp11\alone>jdeps -summary TestClass
Warning: Path does not exist: TestClass

C:\code\java\ocp11\alone>jdeps -summary TestClass.class
TestClass.class -> java.base
TestClass.class -> java.desktop
TestClass.class -> java.sql

Right.
