Sometimes Eclipse will be crazy, good project so compile, even Hello world will report "can't find or can't load the main class " error, I have met several times, previously was lazy to delve into the direct reconstruction project, But the number of times have to delve into the next, now summed up several solutions, you can try according to their own situation.1, because the. java file is not within the SRC path of the project, that is, the source cod

Sometimes, when testing a class, eclipse can be a strange reminder that you can't find the main class. Next there are several workarounds1.
