How to read classes from a jar

Question

I am trying to read classes from a jar. So I started by extracting the files under my jar, I am using JAD decompiler. The decompiler works, for example I have written

System.out.println()

And I have tried to open the class System and it shows the implementation of the class. When trying to read the .class under my jar, I have tried to put the .class under a package, but I can not see the .class under the package, so I have tried to open it like this : File>Open File.., I get the error : The Class File Viewer cannot handle the given input ('org.eclipse.ui.ide.FileStoreEditorInput').

How can I see my .class?

You could open any .class files with Intellij IDE

Why minus? In addition: the Class File Viewer can only open class files which are on the Java build path of a project. – ngranin Jul 07 '20 at 15:23
