Java继承练习

构建Person类（属性：名字、年龄、工作岗位），创建三个对象，并且根据对象的年龄或名字长度来进行冒泡排序

package chapter08.homework.test01;public class homework01 {public static void main(String[] args) {Person[] persons = new Person[3];persons[0] = new Person("tom",66,"软件工程师");persons[1] = new Person("jack",20,"java工程师");persons[2] = new Person("smith",21,"python工程师");for (int i = 0; i < persons.length; i++) {System.out.println(persons[i]);//默认调Person的toString方法}Person tem = null;for (int i = 0; i < persons.length-1; i++) {for (int j = 0; j < persons.length-1-i; j++) {//前面人的年龄小于后面的，就交换
//                if (persons[i].getAge()>persons[i+1].getAge()) {
