First of all, I declare that I really don't have a good relationship with J2ME, and because I have no relationships, there will be a lot of masters.
They look very mentally and honest, huh, huh, I hope everyone will not be BS. At the same time, I hope that the master will also guide the younger brother. Ha ha.
Personal interest, look at J2ME. In fact, it is mainly to help a brother to complete his graduation design. Oh, I don't know him every day.
What is USB busy, anyway, I only know that I will ask him to ask him to go to work. . Forget it, no matter what he. I will wait for him to come back.
.
At present, I have seen things in this area, the first day, I saw some basic concepts of J2ME. Oh, these things have never been exposed to
There is no way, there is no way to have basic concepts. The next day helped him wrote a database operation program running on the PDA. Of course, ten
Simple, huh, huh. On the third day, things have been mutated, more and more, it is good, anyway, I am also interested, huh, huh, so continue to study
Check it. Today I put it on some of the basic concepts that I saw on the first day. Take the time tomorrow to write to the kid
The program on the PDA is put on. Slowly take the process of learning, some ideas and difficulties to learn, and together
share it. Oh, first of all, it is also the most important concept. What is the easiest of J2ME? Not very good, huh, huh, use one
The expression is expressed, J2EE> J2SE> J2ME> Smart Card is also Sun Company to give this Java technology positioning. Of course,
Everything is based on J2SE based on J2SE. (But choose different, some basic types of funds, basic objects will also be different.) Hehe
This is the easiest. Let me talk about how I am watching the information, I have just started a very depressed noun, huh, mainly because I haven't seen it before.
So the first time I have some effort. Take it out, if the people want to learn J2ME, and it is just beginning to learn or have some effect ^ _ ^
1, CLDC: Connected Limited Device Configuration - Applications are limited, such as mobile phones, PDAs.
2, CDC: Connected Device Configuration - Applied on power supply in power, huh, oh, it seems to be top
The box is ^ _ ^ within this range
3. Support for different class libraries, the class library supported by J2ME CLDC is included in the J2ME CDC class library. Relative to J2SE,
They supported class libraries are reduced and have expansion. It is also because of the difference between CLDC and CDC, Java introduces Configuration concept.
. Oh, I want to treat Configuration as the J2ME for the specifications of the two embedded devices. J2ME is for the most important difference from J2SE
The Java.microedition.IO class library has been introduced less than some basic class library support.
4. Profile: profile is the specification of the architecture on the Configuration, and its existence should be to distinguish each
How do Java develop and the features they should have on embedded systems. How to display the use interface of various embedded systems is
Rightening in Profile.
