编写一个JAVA程序片断 定义一个表示学生的类student

精选文库编写一个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 StudentManagepublic static void main(String args) Student myStudent=new Student(1234567,023,hfx,male,21); System.out.println(myStudent.toString();class Studentlong 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 studentprivate 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 Dome4public static
