1. 根据UML图定义Student类:
```
Class: Student
------------------------
- name: String
- age: int
- gender: String
- address: String
- gpa: double
------------------------
+ Student(name: String, age: int, gender: String, address: String, gpa: double)
+ getName(): String
+ getAge(): int
+ getGender(): String
+ getAddress(): String
+ getGPA(): double
+ setName(name: String): void
+ setAge(age: int): void
+ setGender(gender: String): void
+ setAddress(address: String): void
+ setGPA(gpa: double): void
+ toString(): String
```
2. 编写Student类的子类ComparableStudent类,该子类实现Comparable接口,可以按照学生的成绩进行比较。
```
Class: ComparableStudent extends Student implements Comparable<ComparableStudent>
------------------------
+ ComparableStudent(name: String, age: int, gender: String, address: String, gpa: double)
+ compareTo(other: ComparableStudent): int
```
其中,`compareTo`方法实现按照学生的成绩进行比较,返回一个整数值,如果当前对象的成绩大于参数对象的成绩,返回正整数;如果当前对象的成绩小于参数对象的成绩,返回负整数;如果当前对象的成绩等于参数对象的成绩,返回0。例如:
```
@Override
public int compareTo(ComparableStudent other) {
if (this.getGPA() > other.getGPA()) {
return 1;
} else if (this.getGPA() < other.getGPA()) {
return -1;
} else {
return 0;
}
}
```
