java025对象数组的练习

题目：创建一个学生数组，存储三个学生对象并遍历。

分析：

    a：定义一个学生类

    b：创建学生数组

    c：创建学生对象

    d：吧学生对象作为元素赋值给学生数组

    e：遍历学生数组

无参方法快捷键：Source--------Generate  Constructors  form   Superclass

有参方法快捷键：Source--------Generate  Constructor  using  Fields

构造方法getXxx()和setXxx()快捷键：Source--------Generate  Getters  and  Setters

代码实现：

（1）：学生类

package test1;

public class Student {

private String name;

private int age;

public Student() {

}

public Student(String name, int age) {

super();

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;

}

}

测试类：

package test1;

public class StudentDemo {

public static void main(String[] args) {

Student[] students = new Student[3];

//创建学生对象

Student s1 = new Student("李狗子",20);

Student s2 = new Student("英格兰",19);

Student s3 = new Student("老女人",2);

//赋值

students[0] = s1;

students[1] = s2;

students[2] = s3;

for(int x = 0;x<students.length;x++){

Student s = students[x];

System.out.println(s.getName()+"--"+s.getAge());

}

}

}
