用JAVA语言定义一个类，输出学生班级，姓名信息

如题所述

import java.util.ArrayList;
import java.util.List;

public class Student {

public static void main(String[] args) {
List<Students> studentCount = new ArrayList<Students>();//定义一个对象数组存放所有学生的信息
Students firstStudent = new Students();
firstStudent.setGrand("一班");//因为对象里的成员变量是私有的，只能通过SET方法来复制
firstStudent.setName("张三");
studentCount.add(firstStudent);
Students secondStudent = new Students();
secondStudent.setGrand("三班");
secondStudent.setName("王五");
studentCount.add(secondStudent);
for (int index = 0; index < studentCount.size(); index++) {//遍历并通过GET方法取值并输出
System.out.println(studentCount.get(index).getGrand() + " "
+ studentCount.get(index).getName());
}

}

}
/**
* 定义这样的一个Students类存放学生的相关信息
* @author Administrator
*
*/
class Students {
private String name;
private String grand;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getGrand() {
return grand;
}

public void setGrand(String grand) {
this.grand = grand;
}

}
