下面是定义一个JavaBean的代码片断,请完善空白处代码: public class Student { // 成员变量:和姓名 int stuNo ; String stuName ; public int getStuNo() { return stuNo ; } public void setStuNo( stuNo) { this . stuNo = stuNo; } public String getStuName() { return stuName ; } public void setStuName(String ) { this . stuName = stuName; } }
