class Student{ String name; int age; int score=88; Student(String a1, int a2, int a3){ name=a1; age=a3; score=a2; } } 在使用该类时，已使用下面语句生成了该类的对象: Student s1,s2; s1=new student("张三",20,33); s2=new student(); 问题: 1)s1.name，s1.age，s1.score的值各是什么? 2)s2.name，s2.ag

1) 对象s1的属性值为：
- s1.name = "张三"
- s1.age = 33
- s1.score = 20

2) 对象s2的属性值为：
- s2.name = null (未赋值)
- s2.age = 0 (默认值)
- s2.score = 88 (默认值)
