这是Student类

package com.ma_0002;

/**

* 建立一个学生类，重写toString()方法

*/

public class Student {

/************成员变量区****************/

/**学生姓名*/

String name;

/**学生年龄*/

int age;

/************构造方法区****************/

public Student() {

super();

}

super();

this.name = name;

this.age = age;

}

/************get和set方法区****************/

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;

}

/************重写了toString()方法****************/

@Override

}

}

这是测试类StudentTest

package com.ma_0002;

/**

* Student测试类

* @author TP

*

*/

public class StudentTest {

/*

* 需求：

* 创建几个Student对角，并把它们放入一个数组中，然后输出

*

* 分析：

* 1.用Student构造方法创建对象

* 2.创建一个Student[]数组来放对象

* 3.输出

*/

public static void main(String[] args) {

//创建一个学生类对象

Student s = new Student("张大",1);

Student s2 = new Student("张二",2);

Student s3 = new Student("张三",3);

Student s4 = new Student("张四",4);

Student s5 = new Student("张五",5);

Student s6 = new Student("张六",6);

//创建一个Student[]数组来放对象

Student[] stuArr = new Student[6];

//给数组赋值

stuArr[0] = s;

stuArr[1] = s2;

stuArr[2] = s3;

stuArr[3] = s4;

stuArr[4] = s5;

stuArr[5] = s6;

//遍历输出数组元素

for (int i = 0; i < stuArr.length; i++) {

System.out.println("s"+i+" : "+stuArr[i]);

}

}

}

执行结果：

s0 : Student [name=张大, age=1]

s1 : Student [name=张二, age=2]

s2 : Student [name=张三, age=3]

s3 : Student [name=张四, age=4]

s4 : Student [name=张五, age=5]

s5 : Student [name=张六, age=6]
