Сериализация вроде идет, во всяком случае в файле что-то есть. А при десириализации ни чего не поисходит. Поставил для проверки if(objectInputStream.available()!=0), в итоге он его делает где else.
public class ControlPoints extends MyKeyAdapter implements Externalizable {
private static final long serialVersionUID = 1L;
private ArrayList<Point> points = new ArrayList<>();
public ControlPoints(){}
public ControlPoints(ArrayList<Point> points){
this.points = points;
}
private int index=0;
public ArrayList<Point> getPoints() {
return points;
}
private Point takeCoordinates(){
PointerInfo a = MouseInfo.getPointerInfo();
return a.getLocation();
}
public void addPoint(){
points.add(index,takeCoordinates());
index++;
}
@Override
public void writeExternal(ObjectOutput out) throws IOException {
out.writeObject(this.points);
}
@Override
public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException {
points = (ArrayList<Point>) in.readObject();
}
}
это код класса.
Кусок кода заполнения и сохранения:
frame.addKeyListener(new MyKeyAdapter() {
@Override
public void keyPressed(KeyEvent e) {
if (e.getKeyChar() == KeyEvent.VK_1) {
System.out.println("sssss");
controlPoints.addPoint();
}
if (e.getKeyChar() == KeyEvent.VK_2){
Main.savePoints(controlPoints);
System.out.println("saved "+controlPoints.getPoints().get(0).getX());
}
А это Main:
public static void main(String[] args) throws InterruptedException {
ControlPoints p = new ControlPoints();
JFrame.setDefaultLookAndFeelDecorated(true);
new UiJFrame();
try(FileInputStream fileInputStream = new FileInputStream("/home/ivan/IdeaProjects/src/prt1.txt");
ObjectInputStream objectInputStream = new ObjectInputStream(fileInputStream)) {
if(objectInputStream.available()!=0){
while (objectInputStream.available() >0) {
p = (ControlPoints) objectInputStream.readObject();
System.out.println("ioheorg"+objectInputStream.available());
}
}else System.out.println("ne if main 101");
} catch (FileNotFoundException e) {
System.out.println("ein catch");
} catch (IOException e) {
System.out.println("cvein catch");
} catch (ClassNotFoundException e) {
System.out.println("drein catch");
}
if (p!=null){
System.out.println("Tuta "+p.getPoints().get(0).getX());
}
else{
} System.out.println("null%%");
MouseMoving mouseMoving = new MouseMoving(TIME_TO_WAIT);
Thread thread = new Thread(mouseMoving);
thread.start();
}
public static void savePoints(ControlPoints p) {
try (ObjectOutputStream objectOutputStream = new ObjectOutputStream(
new FileOutputStream("/home/ivan/IdeaProjects/src/prt1.txt")
)){
objectOutputStream.writeObject(p.getPoints().get(0));
objectOutputStream.writeObject(p.getPoints().get(1));
} catch (FileNotFoundException e) {
System.out.println("out catch 1");
} catch (IOException e) {
System.out.println("out catch 2");;
}
}
}
