你认为问题可能是来自 IDEA 吗？
英文:
Car.java file
public class Car {
String model;
int year;
int price;
String color;
public Car(String model, int year, int price, String color) {
this.model = model;
this.year = year;
this.price = price;
this.color = color;
}
@Override
public String toString() {
return "Car{" +
"model='" + model + '\'' +
", year=" + year +
", price=" + price +
", color='" + color + '\'' +
'}';
}
}
CarManager.java file
public class CarManager {
public static void main(String[] args) {
Car bmw = new Car("m5", 2020, 50000, "black");
Car rr = new Car("sport", 2019, 70000, "white");
System.out.println(bmw);
System.out.println(rr);
}
}

What do you think is possible can the problem be from IDEA ?

这里有两种可能的选项可以使这段代码正常工作。
- 将Car.java和CarManager.java都放在同一个包中。
或者
- 在CarManager.java中导入Car类。
英文:
There are 2 possible options here to make this code work.
- Place both Car.java & CarManager.java in the same package.
OR
- import class Car in CarManager.java
