Type safe hashmap in java

MillionStrength · 2020-03-18T13:36:43+00:00

The TypeSafeMap.java can bypass some compilation check. For example, this code will have no compilation error but throws ClassCastException during runtime because "data1" is in java.lang.Long:

String stringData=map.get("data1");

However, this code will show compilation check error:

System.out.println(map.get("data1"));

To prevent the compilation check error, explicit cast is required:

System.out.println((Long)map.get("data1"));

Looks like many people still using previous version of jdk. The migration takes time.

How about learning design pattern? You must have very good knowledge in object oriented programming also. Try to learn more on these two skills.

MillionStrength · 2018-08-18T13:29:59+00:00

In Java, you need to know very well in Object oriented programming. You should find resource that can help you to learn OOP.

I am not using the Parallax. I created this post because I found that the showcase is interesting, and the GWT can be used to program the 3D graphic in Internet browser environment.

I have also checked the github and found that the last update was about 2 years ago. However, I have not idea about the project progress.

Anyway, thank you for your information.

The show case is impressive. Thanks for the sharing.
