Estou com problema no meu código. Recebo IOException quando uso readObject em meu código. todo o programa funciona corretamente, mas quando quero usar readObject recebo esta exceção, este é o código que uso para salvar o objeto:
File f = new File("employees.obj");
ObjectOutputStream objOut = null;
try {
objOut = new ObjectOutputStream(new BufferedOutputStream(
new FileOutputStream(f)));
objOut.writeObject(newEmployee);
objOut.flush();
System.out.println("Object is serialized.");
} catch (FileNotFoundException e) {
System.out.println("File not found!");
} catch (IOException e) {
System.out.println("Failed!");
} finally {
if (objOut != null) {
try {
objOut.close();
} catch (IOException e) {
}
}
}
e aqui está o código que uso para restaurar o objeto:
File f = new File("employees.obj");
ObjectInputStream objIn = null;
ArrayList<Employee> c = new ArrayList<Employee>();
try {
objIn = new ObjectInputStream(new BufferedInputStream(
new FileInputStream(f)));
while (objIn.readObject() != null) {
Person employee = (Person) objIn.readObject();
System.out.println("hello");
System.out.println(employee.toString());
}
System.out.println(c.toString());
return c;
} catch (FileNotFoundException e) {
System.out.println("1");
} catch (IOException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
System.out.println("3");
} catch (ClassCastException e) {
System.out.println("4");
} finally {
if (objIn != null) {
try {
objIn.close();
} catch (IOException e) {
System.out.println("4");
}
}
}
return c;
e o resultado no console:
