如何使用枚举的构造函数，实例变量和方法？

解决方法

使用构造函数和调用getPrice()方法显示这个例子中初始化枚举的值。

enum Car {
   lamborghini(900),tata(2),audi(50),fiat(15),honda(12);
   private int price;
   Car(int p) {
      price = p;
   }
   int getPrice() {
      return price;
   } 
}
public class Main {
   public static void main(String args[]){
      System.out.println("All car prices:");
      for (Car c : Car.values())
      System.out.println(c + " costs " 
      + c.getPrice() + " thousand dollars.");
   }
}

结果

上面的代码示例将产生以下结果。

All car prices:
lamborghini costs 900 thousand dollars.
tata costs 2 thousand dollars.
audi costs 50 thousand dollars.
fiat costs 15 thousand dollars.
honda costs 12 thousand dollars.
