编写Student类及测试：含id、name、isMale、birth等私有字段
多动手多思考
public class Student {
private int id;
private String name;
private boolean isMale;
private Date birth;
public Student(int id, String name, boolean isMale, Date birth) {
this.id = id;
this.name = name;
this.isMale = isMale;
this.birth = birth;
}
// getter and setter methods for id, name, isMale, and birth
public int getId() {
return id;
}

this.id = id;
}
public String getName() {
return name;
}

this.name = name;
}
public boolean isMale() {
return isMale;
}
public void setMale(boolean isMale) {
this.isMale = isMale;
}
public Date getBirth() {
return birth;
}
public void setBirth(Date birth) {
this.birth = birth;
}
}
public class StudentTest {
public static void main(String[] args) {
// Instantiate a Student object
Student student = new Student(1, "Alice", false, new Date());
// Access the private fields using getter methods

}
}

// 构造函数
