package demo01;
public class PhoneDemo {public static void main(String[] args) {Phone[] array = new Phone[3];Phone p1 = new Phone("红米Redmi Note 14", 52800, "星辉白");Phone p2 = new Phone("华为 Pura70", 29999, "雪域白");Phone p3 = new Phone("vivo Y37", 49499, "月影黑");array[0] = p1;array[1] = p2;array[2] = p3;int sum = 0;for(int i = 0; i < array.length; i++) {sum += array[i].getPrice();}double avg = (double) sum / array.length;System.out.println("三部手机的平均价格为：" + String.format("%.2f", avg));}
}
