找不到或加载主类

Question

I already searched for this answer and I keep on seeing change your "PATH" but I don't know how to go about doing that. I'm just trying to run this simple code:

package eclipsePackage;

public class TutorialClass {


    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        System.out.println("Hello World");

    }
}

Can someone explain to me thoroughly please. I'm using eclipse and java jre1.8.0_40

Answer 1

我敢打赌，您没有在Eclipse中设置“自动构建”选项，因此当您尝试启动应用程序时，没有任何编译

Answer 2

I don't see anything from the way your code is laid out. Move your java class (without the package statement) into a folder on your C:drive and try running it from the command line. If it works there, then there's probably an issue with your ide. If that's the case, reinstall your ide or revert to the default settings.
