对象数组输出学生信息

注释内是另外一种方式
public class Student {
private int no;
private String name;
private int age;
/public Student(int no, String name, int age) {
// 带参数的构造方法
this.name=name;
this.no=no;
this.age=age;
}/
public Student() {
// TODO Auto-generated constructor stub
}
public int getNo() {
return no;
}
public void setNo(int no) {
this.no = no;
}
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;
}
}
import java.util.Scanner;

public class TestStudent {
public static void main(String[] args) {
// TODO 定义对象数组,使用for循环遍历输出每个学生的年龄
/Student[] stu = new Student[3];//创建对象数组
//创建学生对象
