Take the snake as a child to play for example, for Java Image Interface learning sentiment

Brief introduction:

All the time I've been using code to write graphical interfaces I've never done before, (-?-;), but have chosen to open this road, I think everything is going to be a bit, so maybe it might be a lot easier to re-write things after many months. Moreover, if you forget it later, you can also look at it here, by the way Gao's own literary ability. Forgive me to hit the word more ugly understand, these are more or less exist their own emotions written out, see the text good.

Read after me: This article is suitable for some just get started to learn the graphical interface of Bo friends , of course, more or less understand the basic knowledge of Java (class-related knowledge, generic collection, etc.), otherwise look good. An appendix will be given at the end of the project document. I hate books on a line of shy and difficult to understand the text, a little fresh activity is not, probably and I do not like endorsement has a relationship O (^▽^) O.

This time I will take a game as an example to begin to introduce my own insight into the graphical interface of some knowledge.

Game: Greedy snake;

Development tools: Eclipse Java naon,jdk1.7 above;

Development environment: WINDOWS10 or Ubuntu14.04 (I was compiled under these two platforms, the effect, I was recommended Ubuntu, because I do not know why the windows under the interface is often empty?) To click Run as Java application a lot more, (-?-;) will not necessarily have a game interface appear. If you have bo friends know, hope to be able to guide the younger brother, in this first thank you .

The game interface here (well, like I put on the Ubuntu desktop, Windows can not see, etc will be posted, compared to simple, time relationship, I first say some)

Body:

What is 01.JFrame?

Since it is to write the image interface, then the first to have a framework is cutting! So JFrame is the ancestor of this image interface framework class, so we're going to inherit this class. First in new>>class>>xxxx.class; I suggested that different classes be placed in different packages, so the regulations are clear (this is nonsense). I first name this frame is called Snakefram.java, code see below, look at the comment (knocking on the blackboard);

Snakeframe.class

This is relatively simple, general words jframe this write ok
