[英]I can't read the other objects from file: java.io.streamcorruptedexception: invalid type code: ac
I am trying to read all the saved objects from the file, but I am only able to read the first one and then an exception appears ( java.io.streamcorruptedexception: invalid type code: ac
)我正在尝试从文件中读取所有保存的对象,但我只能读取第一个对象,然后出现异常( java.io.streamcorruptedexception: invalid type code: ac
)
Here is My Code:这是我的代码:
public void loadfile()
{
try{
FileInputStream file = new FileInputStream("accounts.dat");
ObjectInputStream inputfile = new ObjectInputStream(file);
boolean endoffile=false;
while(!endoffile){
try{
accounts2.add((Account) inputfile.readObject());
}catch(EOFException e){
endoffile=true;
}
catch(Exception f){
JOptionPane.showMessageDialog(null, f.getMessage());
}
}
inputfile.close();
}catch(IOException e){
JOptionPane.showMessageDialog(null, e.getMessage());
}
}
public void savefile(){
try{
FileOutputStream file = new FileOutputStream("accounts.dat",true);
ObjectOutputStream outputfile = new ObjectOutputStream(file);
for (int i =0 ; i < accounts.size();i++)
{
outputfile.writeObject(accounts.get(i));
}
outputfile.close();
JOptionPane.showMessageDialog(null, "Succesfully Registered");
this.dispose();
}catch(IOException e){
JOptionPane.showMessageDialog(null, e.getMessage());
}
}
If you try to put the inputfile.readObject() value into a variable then you giving a new value to it in every iteration?如果您尝试将 inputfile.readObject() 值放入变量中,那么您会在每次迭代中为其赋予一个新值吗?
I think that's because there are 2 ObjectOutputStream, and (I'm not sure about this), it's possible that sometimes the first one is not/bad closed... Maybe try to use the same OOS?我认为那是因为有 2 个 ObjectOutputStream,并且(我不确定),有时第一个可能没有/坏关闭......也许尝试使用相同的 OOS?
