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;

this.nianling = n;

}

public String getxuehao(){

return xuehao;

}

public String getbanhao(){

return banhao;

}

public String getxingming(){

return xingming;

}

public String getxingbie(){

return xingbie;

}

public int getnianling(){

return nianling;

}

public String toString(){

return xuehao+" "+banhao+" "+xingming+" "+xingbie+" "+nianling;

}

}

public class Dome4{

public static void main(String args[]){

student s1 = new student("02122168","12","安静","男",24);

System.out.println(s1.toString());

}

}
