Reading Notes: Java2 tutorial (1)

First, I 'd like to say sorry. During this time, because it was close to milestone, the time was very tight, so the content was not updated in a timely manner. In addition, the book thinking in Java, which was launched last time, seems to be too thick and involves many aspects. Besides, due to the background of the author, some methods of description and Chapter arrangement may cause some obstacles to understanding for beginners. Therefore, I found some books of the same type for reference. Therefore, in a period of time, there may be multiple Reading Notes for a certain field for your reference. It is hereby stated.

Now, go to the topic and start taking notes!

Type

Byte

Int

Long

Float

Double
