There are a lot of people want to learn java, java because although fire has been for many years, but its prospects for development is still very good, a large part of people choose to go the direction of java web, java web then what knowledge should be mastered in advance it? Small ape circle Gaga said the following about.
First, identify the direction of their own development. A pc or mobile applications. Fundamentals of time must be serious, although it looks simple but it must be hands to do it. Recommend you a professional java book "java core technology," look carefully, there will be talked about the basics of various types, arrays, linked lists, packaging, and other heavy-duty, and then combine the things mentioned above were to write simple programs, mainly more practice, usually written procedures and more use java, do not be afraid of mistakes, eclipse which will prompt them to learn in error, learning by doing is the best way to learn, to learn basic affirmation.
Secondly, basically Spring, SpringMvc, hibernate, mybatis, struts had to learn about, these are the background frame, foreground basic js, html, css concept to understand. Can write simple js, it will jquery, because java web back-end, and want to do the back-end development, front-end must understand the point.
Also learn about java3 kinds of branches: JavaSE, JavaEE, JavaME.
javaEE, it is the BS out of the Internet architecture, database or to grasp, we must learn html (the most simple static page) after Key learn css (Modify page style, style, font, layout) js (ie javascript, it considered a weakly typed language, but very powerful, you can call the database, page developers will learn to learn it,) then the function is jsp php asp plug some of the pages and the like and the like, can not always be used as a static html page then you must learn to learn after all the java framework.
Java web is now the mainstream big frame 3, commonly known ssh: is strust, spring, hibernate
But not the same with each company, and may only use one, or use two, or a do not have, or have their own separate frame, learning words is just a start, a foundation, a learned, it is another school easy, a lot of knowledge in practical work only to learn to master. Then that is slowly growing in your own work, through practice, to learn some things, such as network applications work, we must use some shelf package.
These are some of the things you want to learn java web ought to know, want to learn java web first clear their own direction, after clear, to know what is the need to master, something you can understand, only know ourselves, to know yourself, confused students can in a small circle apes learn about a systematic approach to learning, as long as the development of a plan for yourself and stick to it, you can learn, come on!
