a1.add(f1);在Java中什么意思？

Question

public class Example{
public static void main(String[] args) {
Flower f1 = new Flower("玫瑰花","路易十四","深紫色",400);
Flower f2 = new Flower("玫瑰花","朱丽叶","淡茶色",300);
Flower f3 = new Flower("百合花","地平线","花橙色",450);

Flower[] a1 = new Array[3];
a1.add(f1);
a1.add(f2);
a1.add(f3);

Answer 1

add一般都是往集合中添加元素

Answer 2

这个感觉是错的吧，如果用数组应该是a1[0] = f1;a1[1] = f2;......
或者用集合List<Flower> a1 = new ArrayList<Flower>();
a1.add(f1);
a1.add(f2);
a1.add(f3);

Answer 3

创建一个Flower 类型的数组，长度为3；创建3个Flower 类，依次添加到数组里边

Answer 4

添加元素到集合里
