How do I add an existing .class to an existing eclipse project?

Question

how do I add an existing class into an existing project. I've got the file "Something.class" and in the code I do a

something window = new Something();

But it remains underlined in red. Does someone know how do I fix this?

Thanks!!

Answer 1

If it's not already part of your workspace, it should be enough just to File -> Import and then find the class you want included. If it's already part of the workspace, then Tommi's suggestion should do it.

Answer 2

Also note, that Java is case sensitive. So in

something window = new Something();

something and Something are two different classes :)

Answer 3

You need to import the class into the referencing class. Ctrl + Space (while highlighting the classname) should do the trick in Eclipse.

Answer 4

您需要添加具有类的jar文件something到你的项目，并导入你的类。
