Java练习:创建一个Person类 ，其定义如下？
public class Person{
private String name;
private int age;
private int sex;
public Person(){
this.age = 1;
this.sex = 0;
}
public Person(String name,int age,int sex){
this.name = name;
this.age = age;
this.sex = sex;
}
}
JAVA 定义Person类
public class Person {
private String name;
private int age;
Person(String name ,int age){
this.name = name;
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Override
public String toString() {
return "name="+name+",age="+age;
}
}
public class Student extends Person {
private String id;
private String school;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getSchool() {
return school;
}
public void setSchool(String school) {
this.school = school;
}
Student(String name, int age,String id ,String school) {
super(name, age);
this.id = id;
this.school=school;
}
public void Hello (){
System.out.println("Hello"+ this.school + super.getName());
}
@Override
public String toString() {
return "school="+this.school+",id="+this.id+","+super.toString();
}
}
public class Test {
public static void main(String[] args) {
Person person = new Person("hanmeimei", 21);
System.out.println(person);
Student student = new Student("Lilei", 22, "ID01", "希望小学");
System.out.println(student.toString());
}
}
用java语言定义一个Person类
class Person{
private String name;
private String sex;
}
class Student extends Person{
private int age;
private int score;
public Student(String n,String s,int a,int score){
super(n,s);
this.age=a;
this.score= score;
}
}
用java创建一个person类，包含姓名，年龄属性
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
public class Person {
private String name;
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public static void main(String[] args) {
ListPerson persons = new ArrayListPerson();
Scanner scanner = new Scanner(System.in);
while(true){
Person person = new Person();
System.out.println("请输入姓名：");
String name = scanner.next();
System.out.println("请输入年龄：");
int age = scanner.nextInt();
person.setName(name);
person.setAge(age);
persons.add(person);
System.out.println("继续输入：y/n?");
String cmd = scanner.next();
if("n".equalsIgnoreCase(cmd)){
break;
}
}
System.out.println("共输入"+persons.size()+"人");
int sum = 0;
for(Person p:persons){
sum += p.getAge();
}
System.out.println("平均年龄："+(1.0*sum/persons.size()));
}
}
