How can I display the possible commands for an imported Java package?
For example, when import javax.swing.*, is there any way to display what all is imported here? Ideally I'd like to do it within the code, using a simple System.out.println() to display all the functions that are imported with the *. Thanks in advance.

You can't do this with code.
Packages do not exist in Java when the code is executed. Packages are a mechanism for programmers to structure their programs and organise them logically but when the Java Virtual Machine loads a Java program it does not separate out the classes into packages in the same way.
There are some very complicated long winded attempts out there at providing this functionality but it requires restructuring your design and causing considerable impact on your program so it isn't advised, Java just isn't designed to provide this information, it's more hassle than its worth. The Java API documentation [1] lists all the classes and methods that are available in the standard java packages.
