Question

JAVA中将控制台动态输入的一组学生数据存储到数组student中怎么实现

学生类

public class Student {
public int id;
public String name;
public boolean gender;
public int age;
public String classteam;
public Student(int id,String name,boolean gender,int age,String classteam){

this.id = id;
this.name = name;
this.gender = gender;
this.age = age;
this.classteam = classteam;
}

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public boolean isGender() {
return gender;
}
public void setGender(boolean gender) {
this.gender = gender;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getClassteam() {
return classteam;
}
public void setClassteam(String classteam) {
this.classteam = classteam;
}
}
学生管理类实现动态数据的输入并存储至文本文档
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStreamReader;

public class StudentManager {

private final static int MAX_SIZE = 10;
private int length;

public StudentManager(){
length = 0;
}

public void display() throws IOException{
/**
* 采用控制台动态输入数据
*/
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
BufferedWriter bw=new BufferedWriter(new FileWriter("D:\\学生情况.txt"));

String s1,s2,s3,s4,s5;
while(length < MAX_SIZE)
{
System.out.println("学生学号：");
s1=br.readLine();
if(s1.length()==0)
break;
System.out.println("学生姓名：");
s2=br.readLine();
if(s2.length()==0)
break;
System.out.println("学生性别：");
s3=br.readLine();
if(s3.length()==0)
break;
System.out.println("学生年龄：");
s4=br.readLine();
if(s4.length()==0)
break;
System.out.println("学生所在班级：");
s5=br.readLine();
if(s5.length()==0)
break;

bw.write(s1);
bw.write(" ");
bw.write(s2);
bw.write(" ");
bw.write(s3);
bw.write(" ");
bw.write(s4);
bw.write(" ");
bw.write(s5);

bw.newLine();//产生新行
length++;
}
bw.close();
}

}
如何实现将动态输入的数据存储至一个学生类数组？
各位高手些帮帮忙啊`````

Answer 1

public class Student {
public int id;
public String name;
public String gender;
public int age;
public String classteam;
public Student(int id,String name,String gender,int age,String classteam){

this.id = id;
this.name = name;
this.gender = gender;
this.age = age;
this.classteam = classteam;
}

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String isGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getClassteam() {
return classteam;
}
public void setClassteam(String classteam) {
this.classteam = classteam;
}

public String toString()
{
return "id="+id+",name="+name+",sex="+gender+",age="+age+",class="+classteam;
}
}
