 1 public class Flower {
 2     private String string;
 3     private int age;

 5     public Flower() {
 6         // 先调用public Flower(String string, int age)
 7         this("leon", 120);
 8         // 先调用public Flower(String string, int age)
 9     }
10     public Flower(String string) {
11         this(string, 12);

14     public Flower(String string, int age) {
15         this.string = string;
16         this.age = age;
17         System.out.println("姓名:" + this.string + " 年龄: " + this.age);
18     }

23         Flower flower2 = new Flower("leon", 12);
