Error: Could not find or load main class .data.mfs.usercode.85.java.15011318864936pbkgtpz8.HelloWorld
public class HelloWorld{ public static void main(String[] args) { double avg1=78.5; int rise=5; double avg2=avg1+rise; System.out.println("考试平均分："+avg1); System.out.println("调整后的平均分："+avg2); } } 有错吗？
