Autumn

Today, I took the subway to get to the office. There are many people. Someone is standing with newspapers and someone sits and see the DMB.

I also read the books which is the Effective Java second edition. I like this book , this book has a lot of very useful subjects regarding Java language.

In particular, the useful Java patterns like singleton, builder, and immutable class are very unique and interesting parts in this book.

I also hope to write the similar technical book to share my information and expertise with people in the future.
