If I have a .class file, how do I open it/view the source code? I think I have to decompile it first, but how the heck do I do that?

Just drag the .class file into your ide and it should show you the contents of that file, or you can use this http://www.javadecompilers.com/ to decompile the .class file.:)

Does the IntelliJ IDEA provide access to compiled “.class” files or decompiled “.class” files? I’m enrolled in a course that requests for students to submit compiled “.class” files.
IntelliJ does not produce any .class until you make your project

After making your project the class files will be in Target folder:

I open this file with ANSIC code,so how can I solve this problem?
That is not Java source code.
.class files are compiled Java binary class files.
.java files have the source code.
If you are looking for the source code of the Java compiler (javac), you can get that from OpenJDK. But it's a big and complex project.

In C/C++, the .exe file is automatically generated by the compiler when we run the code.
My question is how do you generate the .exe file in Java instead of just hitting run every time when we open up the .java file.
To do that, you'd need to create an Executable .jar file. Here's the instructions on how to do it.

That's basically it...How do I create it?? I've been trying to find it and googling for it but found nothing yet...maybe I'm just overlooking it...but I already got sort of desperate...
Right click in the file tree, new->File.
give it the suffix .properties and it will act as a properties file.
