JAVA编程题第二小题 定义一个学生类CStudent？

~ import java.util.concurrent.atomic.AtomicInteger;

public class CStudent {

/**
* 姓名
*/
private String name;
/**
* 性别
*/
private String gender;

/**
* 年龄
*/
private Integer age;

/**
* 学号
*/
private String studentNo;

/**
* 学生数量
*/
private static AtomicInteger studentNum = new AtomicInteger(0);

public CStudent() {
studentNum.incrementAndGet();
}

/**
* 获取学生数量
* @return
*/
public static int getStudentNum() {
return studentNum.intValue();
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getGender() {
return gender;
}

public void setGender(String gender) {
this.gender = gender;
}

public Integer getAge() {
return age;
}

public void setAge(Integer age) {
this.age = age;
}

public String getStudentNo() {
return studentNo;
}

public void setStudentNo(String studentNo) {
this.studentNo = studentNo;
}

@Override
public String toString() {
return "CStudent [name=" + name + ", gender=" + gender + ", age=" + age + ", studentNo=" + studentNo + "]";
}

}
其他的相对简单，就不写了
