Student的测试类: package com.itheima; /* * 创建一个学生数组,存储三个学生对象并遍历 * * 分析: * A:定义学生类 * B:创建学生数组 * C:创建学生对象 * D:把学生对象作为元素赋值给学生数组 * E:遍历学生数组 */ public class StudentDemo { public static void main(String[] args) { //创建学生数组 Student[] students = new Student[3]; //创建学生对象 Student s1 = new Student("曹操",40); Student s2 = new Student("刘备",35); Student s3 = new Student("孙权",30); //把学生对象作为元素赋值给学生数组 students[0] = s1; students[1] = s2; students[2] = s3; //遍历学生数组 for(int x=0; x<students.length; x++) { Student s = students[x]; //System.out.println(s); System.out.println(s.getName()+"---"+s.getAge()); } } }
