My program is just a simple System.out.println(\"\"); But netbeans cannot find the main method. Is netbeans 6.7.1 conflict with WIN7? Any possible error?
I had this issue as well (Error: Could not find or load main class test.Test). I'll explain this relatively basically since I know I would have appreciated someone doing that when I was looking for my answer.
When I right-clicked on the project (left hand side of the screen unless you got rid of the projects tab) and went to properties and then run, the main class had the projectname.classname, which is what confused me. For example, I created a project "test" to test this out, and when I went to
(right-click) test or Source Packages -> properties -> run -> main class
had Test.test in that field, which is what the problem was. the class is test, not Test.test, so I clicked browse to its right, and the only thing in the list to select from was test, and when I selected that and tried rerunning it, it finally worked.
Additionally, I found that when you create a new project in Netbeans, one of the things it originally gives you (in my case of the project named test) is package test;. If you are having this problem, then like me, you probably originally got rid of that line seeing it as just another line of code you didn't need. That line of code is what enabled your main class which in my case was Test.test to find the main class *test from that.
