Code snippet about saving and loading on JAVA by using serialization. In this one, i prefer to save/load an arraylist. You can customize it.

Serialization.java

public static void savingArrayList(File saveFile , ArrayList<MyClass> myArrayList ){
 try {
 FileOutputStream fos = new FileOutputStream(saveFile);
 GZIPOutputStream gzos = new GZIPOutputStream(fos);
 ObjectOutputStream out = new ObjectOutputStream(gzos);
 out.writeObject(myArrayList);
 out.flush();
 out.close();
 }catch (IOException e) {
 System.out.println(e);
 }
 }
 public static void loadingArrayList(File selectedFile){
 try {
 FileInputStream fis = new FileInputStream(selectedFile);
 GZIPInputStream gzis = new GZIPInputStream(fis);
 ObjectInputStream in = new ObjectInputStream(gzis);
 ArrayList<MyClass> myNewArrayList = (ArrayList<MyClass>)in.readObject();
 in.close();
 }catch (Exception e) {System.out.println(e);
 }
