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;}@Overridepublic String getName() {return name;}@Overridepublic void setName(String name) {this.name = name;}
}
