Recently, I ran some of my java code, and it gave the warning text:

Editor does not contain a main type

While searching, I realized that some people added some command lines in my sample above. But I don’t think it is the best way to correct the problem – editor does not contain a main type in eclipse
How would you explain this trouble? or Is there a better way?
Below is the detail of the command that I used:

public class Sample{
 
  public static void main(String[] args){
  System.out.println("YOLO");
  }
 }
