1. 直接new一個物件
MyObject object = new MyObject();2. 取得class後newInstance()
MyObject object = MyObject.class.newInstance();
MyObject object = (MyObject) Class.forName("package.MyObject").newInstance();
MyObject object = (MyObject) Class.forName("package.MyObject").getDeclaredConstructor().newInstance();3. 取得Constructor後newInstance()
Constructor<MyObject> constructor = MyObject.class.getConstructor();
MyObject object = constructor.newInstance();4. 使用Clone
MyObject anotherObject = new MyObject();
MyObject object = (MyObject) anotherObject.clone();5. 使用input stream反序列化
ObjectInputStream inStream = new ObjectInputStream(anInputStream);
MyObject object = (MyObject) inStream.readObject();
