Question

新手JAVA 程序，大家帮我看看我这程序错在哪了

package com;

import java.io.*;

public class Main {

BufferedReader br=new BufferedReader(new InputSteamReader(System.in));

IdVO all[]=new IdVO[3];

void start()
{

try
{
for(int i=0;i<all.length;i++)
{

IdVO aIdVO()=new IdVO();

System.out.println("请输入姓名：");
aIdVO.setName(br.readLine());

System.out.println("请输入年龄：");
aIdVO.setAge(Integer.parseInt(br.readLine()));

System.out.println("请输入性别：");
aIdVO.setSex(Integer.parseInt(br.readLine()));

System.out.println("请输入学号：");
aIdVO.setId(br.readLine());

all[i]=aIdVO;

}

for(int i=0;i<all.length;i++)
{
System.out.println("姓名"+aIdVO.getName(i+1)+"年龄"+aIdVO.getAge(i+1)+"性别"+aIdVO.getName(i+1)+"学号"+aIdVO.getName(i+1)) ;
}
}
catch(Exception e)
{
e.printStackTrace();
}

}
public static void main(String[] args) {
new Main().start();
}
}

-----------------------------------------------------------------
package com;

class IdVO {
private String name;
private int age;
private String sex;
private int id;

public void setName(String name) {
this.name = name;
}

public void setAge(int age) {
this.age = age;
}

public void setSex(String sex) {
this.sex = sex;
}

public void setId(int id) {
this.id = id;
}

public String getName() {
return (this.name);
}

public int getAge() {
return (this.age);
}

public String getSex() {
return (this.sex);
}

public int getId() {
return (this.id);
}
}

哪位大侠能帮我修改下
修改了下Main.java，但是还是不行

import java.io.*;

public class Main {

BufferedReader br=new BufferedReader(new InputSteamReader(System.in));//显示出错

IdVO all[]=new IdVO[3];

void start()
{

try
{
for(int i=0;i<all.length;i++)
{

IdVO aIdVO=new IdVO();

System.out.println("请输入姓名：");
aIdVO.setName(br.readLine());

System.out.println("请输入年龄：");
aIdVO.setAge(Integer.parseInt(br.readLine()));

System.out.println("请输入性别：");
aIdVO.setSex(br.readLine());

System.out.println("请输入学号：");
aIdVO.setId(Integer.parseInt(br.readLine()));

all[i]=aIdVO;

}

for(int i=0;i<all.length;i++)
{
System.out.println("姓名"+aIdVO.getName(i)) ; //这里怎么写，没弄明白
}
}
catch(Exception e)
{
e.printStackTrace();
}

}

Answer 1

1.InputStreamReader 你少个r
2.IdVO aIdVO()=new IdVO(); 改为IdVO aIdVO=new IdVO(); 去掉对象名后的两个括号
3.System.out.println("请输入年龄：");
aIdVO.setAge(Integer.parseInt(br.readLine()));
System.out.println("请输入性别：");
aIdVO.setSex(br.readLine());
年龄是整数 性别是字符串
4.System.out.println("姓名"+all[i].getName()+"年龄"+all[i].getAge()+"性别"+all[i].getName()+"学号"+all[i].getName()) ;
这是我修改后的代码 通过了
package com;

import java.io.*;

public class Main {

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

IdVO all[]=new IdVO[3];

void start()
{

try
{
for(int i=0;i<all.length;i++)
{

IdVO aIdVO=new IdVO();

System.out.println("请输入姓名：");
aIdVO.setName(br.readLine());

System.out.println("请输入年龄：");
aIdVO.setAge(Integer.parseInt(br.readLine()));

System.out.println("请输入性别：");
aIdVO.setSex(br.readLine());

System.out.println("请输入学号：");
aIdVO.setId(Integer.parseInt(br.readLine()));
all[i]=aIdVO;
}

for(int i=0;i<all.length;i++)
{

System.out.println("姓名"+all[i].getName()+"年龄"+all[i].getAge()+"性别"+all[i].getName()+"学号"+all[i].getName()) ;
}
}
catch(Exception e)
{
e.printStackTrace();
}

}
public static void main(String[] args) {
new Main().start();
}
}

package com;

class IdVO {
private String name;
private int age;
private String sex;
private int id;

public void setName(String name) {
this.name = name;
}

public void setAge(int age) {
this.age = age;
}

public void setSex(String sex) {
this.sex = sex;
}

public void setId(int id) {
this.id = id;
}
