Eclipse错误：无法找到或加载主类

Question

I have an Interface class checked out from an svn project, and created an Interface_Tester class to preview the interface. However, when I try to run it in Eclipse I get the following error:

Error: Could not find or load main class Interface_Tester

Here is the code from the interface_tester class -

public class Interface_Tester {
    public static void main(String[] args){
        Interface test = new Interface();
    }
}

I have seen a similar question asked on here but did not understand the answer. I need a step-by-step guide to the solution as I am a beginner. Thank you

UPDATE: I tried running the Interface class itself and had the same error... All classes are being shown in the project explorer on the left so why is eclipse unable to locate any of them?

Answer 1

On the left side of Eclipse you have a project view. Try right-clicking your Interface_Tester from there and in a dropdown choose run. May be you you are trying to run something else
