问题描述：测试对象流，今早经老师指点解决了乱码问题，然后重新写了一遍代码，和之前一模一样结果抛出异常打印的数据也只有一个是对的，老师这是编码问题吗？
代码如下：
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
public class Test2 {
public static void main(String[] args) {
//write();
read();
}
private static void read() {
//创建对象流对象
ObjectInputStream ois=null;
try {
ois = new ObjectInputStream(new FileInputStream("D:\\object33.txt"));
//读取数据，读取数据顺序必须和写入顺序完全一致否则报错
System.out.println(ois.readBoolean());
System.out.println(ois.readDouble());
System.out.println(ois.readChar());
System.out.println(ois.readUTF());
Person p=(Person)ois.readObject();//转换成Person类型
System.out.println(p);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally {
if(ois!=null) {
try {
ois.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
private static void write() {
//创建对象流对象
ObjectOutputStream oos=null;
try {
oos = new ObjectOutputStream(new FileOutputStream("D:\\object33.txt"));
//写入数据
oos.writeBoolean(true);
oos.writeDouble(99.99);
oos.writeChar(97);
oos.writeUTF("闲来垂钓碧溪上，忽复乘舟梦日边");
oos.writeObject(new Person("临江仙",20));
//oos.flush();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally {
if(oos!=null) {
try {
oos.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
异常如下：
