JAVA程序编写一个学生类Student

1）学生类Student属性有：
id;long型，代表学号
name;String类对象，代表姓名
age;int型，代表年龄
sex;boolen型，代表性别
（其中：true表示男，false表示女）
phone;String类对象，代表联系电话
（2）学生类方法有：
Student(long i,String n,int a,boolean s,long p):有参构造函数，形参表中的参数分别初始化学号、年龄、性别和联系电话。
int getAge()( ):获取年龄作为方法的返回值。
long getphone( ):获取联系电话作为方法的返回值。
public String toString( ):以姓名：联系电话的形式作为方法的返回值。

Public Class Student{
Public long id;
Public String name;
Public int age;
Public boolean sex;
Public long phone;
Public Student(long i,String n,int a,boolean s,long p){
this.id = i;
this.name = n;
this.age = a;
this.sex = s;
this.phone = p;
}
Public int getage(){
return this.age;
}
Public long getphone(){
return this.phone;
}
Public String toString(){
return this.name;
}
Public static void main(String[]args){
Student student = new Student(01,"李明",20,true,13xxx);
System.out.println(student.age());
System.out.println(student.getphone());
System.out.println(student.toString());
}
}

public class student{ private string name; private int xh; public student(){} public student(string name, string xh){ this.name = name; this.xh = xh; } public string getname(){ return name; } public string getxh(){ return xh; } public void setname(string name){ this.name = name; } public void setxh(string xh){ this.xh = xh; } public void print(){ system.out.println("my name is "+name+",xh is"+xh+"); } }

//以下是程序段在自己机子上已经编译运行过了你自己试下 public class Student{ public long id; public String name; public int age; public boolean sex; public long phone; public Student(long i,String n,int a,boolean s,long p){ this.id = i; this.name = n; this.age = a; this.sex = s; this.phone = p; } public int getage(){ return this.age; } public long getphone(){ return this.phone; } public String toString(){ return this.name; } public static void main(String[]args){ Student student = new Student(01,"李明",20,true,8888); System.out.println(student.getage()); System.out.println(student.getphone()); System.out.println(student.toString()); } }

咋不自己写呢
