java Hello World 错误：在类名中找不到主方法，请将主方法定义为：public static void main(String[] args)

Question

I don't understand why I'm getting an error here code below:

public class Lab1HW { public static void main(String[] args) {

    System.out.println("Computer Science, Yes!!!!");        
    
}

}

Answer 1

do following steps: write code as:

    public class Lab1HW{

  public static void main(String[] args){

      System.out.println("Computer Science, Yes!!!!");        
    
}
}

then save file using same name as class name. in you case Lab1HW.java then you have to compile and run.. output will be

Computer Science, Yes!!!!

Answer 2

your code seems fine, just try writing it this way or first try running it on an online compiler.

public class Lab1HW{

  public static void main(String[] args){

      System.out.println("Computer Science, Yes!!!!");        
    
}
}
