【正文】 est barrier The remendation looked Wang Sen the Java Depth Experiences dangers has carried on the thorough discussion to these two questionsSecond step is studies Java the grammar The Java grammar is kind of C the basically mainstream programming language is not kind of C is kind of C does not have what new thing therefore the grammar study probably was the quite a while time is enough Only needs to pay attention is has the key words usage which several is not easy to make clear public protected private static when uses why has to use how uses this possible need some people to direct I initially was own ponder over pletely has spent the very long time But afterwards I saw above this book spoke these concepts to Thinking in JavaThird step is studies Java the objectoriented programming language characteristic place For instance inherits structure abstract class the connection the method are many condition heavy load cover Java exception handling mechanism Said regarding a not objectoriented language background person that I thought this process needs to spend the very long very long time because studies in front of Java does not have C the experience only then the C experience I was have probably spent for a month all made clear only then thoroughly these concepts book example above repeatedly estimating the revision the attempt repeatedly looked at that several chapter of contents looked looked has not gotten down 5 prehended only then thoroughly But I thought if has the C experience should 12 days time be enough Then in this process may have a look Thinking in Java this book opposite is extremely thorough to the object explanation What a pity is I studies has not seen to this book therefore own have spent the massive time and estimates through own attempt learnsFourth step starts a familiar Java kind of storehouse The Java foundation class storehouse actually is JDK installs under the table of contents jre\Lib\RtJar this package The study foundation class storehouse studies rtJar Inside the foundation class storehouse kind are extremely extremely many It is said some more than 3000 I have not counted But said the most core truly regarding us only then 4 respectively is JavaLang JavaIo JavaUtil JavaSql These four packages study each package study all may write thick teaching material but Oreilly also truly is does this I thought if time quite tight is impossible through to read four books to study I thought the quite good study method is such First must read through entire package the frame understood entire package class interface the exception constitution should better be can find the introduction entire package frame the article These introduced specially package of books the first several chapters should be these overall frame content introductions Is not must be familiar with each kind of usage to the package of overall frame assurance which attributes remembers it have the method Wants to record also cannot remember But is must know which aspects the package does have a kind of constitution these kind of uses are any most core several classifications maybe plete any function I in the time which trains to the human generally is a class speaks a package therefore not impossible detailed introduction each kind of usage but I repeatedly stress how do I speak these packages to you am must tell you a kind of method am transfer also does not request you to remember the kind of method transfer but wants you to understand which kinds Java has provided to us each kind is uses in any situation when I meet the question the time I knew which kind or which several kind of binations can solve my problem Thatall When we write the procedure specifically time so long as you knew which kind should plete your work with to be enough Codes the concrete method transfer writes the code Documentation all things all inside Documentation will not request you certainly to remember are actual you also not to be able to remember more than 3000 kinds altogether the nearly 100000 methods transfers Therefore changes to each package overall frame assurance extremely importantlyFifth step through above study if study the quite solid speech built the Java foundation is left over the work which had to do is sweeps clean inside Documentation besides above 4 packages other some parisons to have the use the kind Believed progressed to this step Java studies independently the ability already to raise might to study Documentation directly horizontal Besides must make the GUI programming inside JDK other can have the use the package is these JavaText JavaNet JavaxNaming These packages of inside real correct uses quite many kinds very are actually few only then several therefore does not need to spend the very much timeSixth step Java Web programming The Web programming core is the HTTP agreement the HTTP agreement and Java irrelevant if not familiar HTTP agreement although also may learn ServletJSP programming but cannot achieve extrapolates by knowing one method you will know all boundary Therefore the HTTP agreement study is necessary If has been familiar with HTTP agreement also had the Java programming good foundation studies ServletJSP is simply easy as pie I study ServletJSP has used not to weeklong time then started with JSP to make the project In ServletIn the JSP study heavy still was Servlet Documentation Servlet the API most monly used kind are very few the flowered quite few time might grasp These kinds all looked at writes several examples to try ServletThe JSP programming essence is transferring these kinds to e repeatedly through the HTTP agreement converses between Web Server and Brower Moreover to JSP but also needs to be familiar with several monly used JSP the mark the concrete mode of writing cannot remember the speech looks up temporaril
