编写一个JAVA程序片断-定义一个表示学生的类student.docxVIP

编写一个JAVA程序片断 定义一个表示学生的类student,包括域学号,班级,姓名,性别,年龄;方法获得学号,获得班号,获得姓名,获得性别,获得年龄,修改年龄. 程序如下: import java.lang.String;import java.lang.System;import java.io.*; public class StudentManage{public static void main(String args[]){?? Student myStudent=new Student(1234567,023,hfx,male,21);?? System.out.println(myStudent.toString());}} class Student{long studentNumber;String classNumber;String studentName;String studentSex;int studentAge;Student(long a,String s,String d,String f,int h){??? studentNumber=a;??? classNumber=s;??? studentName=d;??? studentSex=f;??? studentAge=h;}void getNumber(long sno,String sna){???? if(studentName==sna)??? studentNumber=sno;?? else??? System.exit(1);???}void getName(long sno,String sna){?? if(studentNumber==sno)??? studentName=sna;?? else??? System.exit(1);}void getClass(long sno,String sna,String cn){?? if(studentNumber==sno||studentName==sna)??? classNumber=cn;?? else??? System.exit(1); }void getSex(long sno,String sna,String s){?? if(studentNumber==sno||studentName==sna)??? studentSex=s;?? else ??? System.exit(1); }void getAge(long sno,String sna,int a){?? if(studentNumber==sno||studentName==sna)??? studentAge=a;?? else??? System.exit(1); }int changeAge(int a){?? studentAge=a;?? return studentAge; }public String toString(){?? String s=studentNumber:+studentNumber??? +\n studentName:+studentName??? +\n classNumber:+classNumber??? +\n studentSex:+studentSex??? +\n studentAge:+studentAge; ?? return s;}} =================================================================================== 编写一个Java程序片断，以定义一个表示学生的类Student。这个类的属性有“学号”、“班号”、“姓名”、“性别”、“年龄”，方法有“获得学号”、“获得班号”、“获得性别”、“获得姓名”、“获得性别”、“获得年龄”。 class student{private String xuehao;private String banhao;private String xingming;private String xingbie;private int nianling;public student(String x,String b,String m,String b1,int n){?? this.xuehao = x;?? this.banhao = b;?? this.xingming = m;?? this.xingbie = b1;
