JSON(JavaScript Object Notation) 是一種輕量級(jí)的數(shù)據(jù)交換格式。易于人閱讀和編寫。同時(shí)也易于機(jī)器解析和生成。它基于JavaScript(Standard ECMA-262 3rd Edition - December 1999)的一個(gè)子集。 JSON采用完全獨(dú)立于語(yǔ)言的文本格式,但是也使用了類似于C語(yǔ)言家族的習(xí)慣(包括C, C++, C#, Java, JavaScript, Perl, Python等)。這些特性使JSON成為理想的數(shù)據(jù)交換語(yǔ)言。[編輯本段]JSON與XML的比較 ◆可讀性 JSON和XML的可讀性可謂不相上下,一邊是建議的語(yǔ)法,一邊是規(guī)范的標(biāo)簽形式,很難分出勝負(fù)。 ◆可擴(kuò)展性 XML天生有很好的擴(kuò)展性,JSON當(dāng)然也有,沒有什么是XML能擴(kuò)展,JSON不能的。 ◆編碼難度 XML有豐富的編碼工具,比如Dom4j、JDom等,JSON也有json.org提供的工具,但是JSON的編碼明顯比XML容易許多,即使不借助工具也能寫出JSON的代碼,可是要寫好XML就不太容易了。 ◆解碼難度 XML的解析得考慮子節(jié)點(diǎn)父節(jié)點(diǎn),讓人頭昏眼花,而JSON的解析難度幾乎為0。這一點(diǎn)XML輸?shù)恼媸菦]話說(shuō)。

Java has become a confusing world. Five years ago, there were few decisions to make once you started programming in Java—you used AWT for graphical user interfaces, sockets for network programming, and hacked together everything else you needed. Since then, though, the APIs available for the Java language have grown, and grown. . . and grown. Now you can dabble in Swing, servlets, Enterprise JavaBeans (EJB), JavaMail, and more. Additionally, there are now packages of APIs, like the Java 2 Micro Edition (J2ME) and Java 2 Enterprise Edition (J2EE). While these packages seem to be nicely wrapped bundles of useful APIs, they don t help the average developer figure out how to piece together the APIs contained in these packages. Though it s simple to find documentation on the individual APIs, getting the "big picture" is difficult, at best. One of the most interesting, but difficult, aspects of Java today is building Java enterprise applications using the J2EE package.
