代码实现

首先定义Person类（人类）

/**
 * 人的基础特征
 *
 * @author Admin
 */
public class Person {

    /**
     * 姓名
     */
    String name;

    /**
     * 生日
     */
    Date birthday;

    /**
     * 手机号码
     */
    String tel;

    /**
     * 身份证号码
     */
    String idCode;

    public Person() {
    }

    public Person(String name, Date birthday, String tel, String idCode) {
        this.name = name;
        this.birthday = birthday;
        this.tel = tel;
        this.idCode = idCode;
    }

    public String getName() {
        return name;
    }

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

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    public String getTel() {
        return tel;
    }

    public void setTel(String tel) {
        this.tel = tel;
    }

    public String getIdCode() {
        return idCode;
    }

    public void setIdCode(String idCode) {
        this.idCode = idCode;
    }
}

其次，定义Student类（学生类）继承Person类（人类） 

/**
 * 学生的基本特征
 *
 * @author Admin
 */
public class Student extends Person {

    /**
     * 学号
     */
    private String studentId;

    public Student() {
    }

    public Student(String name, Date birthday, String tel, String idCode) {
        super(name, birthday, tel, idCode);
    }

    public Student(String name, Date birthday, String tel, String idCode, String studentId) {
        super(name, birthday, tel, idCode);
        this.studentId = studentId;
    }

    public String getStudentId() {
        return studentId;
    }

    public void setStudentId(String studentId) {
        this.studentId = studentId;
    }
}

最后，调用Student全参构造方法测试

public class Test {
    public static void main(String[] args) {
        Student student = new Student("张三",
                new Date(),
                "10086",
                UUID.randomUUID().toString(),
                System.currentTimeMillis() + "");
        System.out.println("名字:" + student.getName());
        System.out.println("生日:" + student.getBirthday());
        System.out.println("手机号码:" + student.getTel());
        System.out.println("身份证号:" + student.getIdCode());
        System.out.println("学号:" + student.getStudentId());
    }
}

什么是super

在派生类（子类）中想要调用超类（父类）的属性或方法是，用super代指超类对象，例如当前类的属性名与超类的属性名相同，为了便于区分，引入super关键字，示例如下：

public class Person {

    private String name;

    public Person(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

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

public class Student extends Person {

    private String name;

    public Student(String name, String name1) {
        super(name); // 调用父类构造方法
        this.name = name1;
    }

    @Override
    public String getName() {
        return name;
    }

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