上課時一般學生都會問這兩個版本的考試有什麼區別，我這裏有個資料可以看看
JAVA[tm] PROGRAMMER EXAMS
> What are the differences between Sun Certified Programmer for Java 2 Platform 1.2 (CX-310-025) and 1.4 (CX-310-035) exams?
> All AWT objectives have been removed (there will be no questions on GUI programming). > All I/O objectives have been removed. //1.4中 AWT 、I/O都不考了
> An objective on Assertions has been added. //新加了Assertions的考查內容，這個在新的中文教材裏有，老的英文教材沒有。
> A few of the previous objectives have been strengthened (so you can expect more/more detailed questions of them). They include: hashcode and equals, Collections, Wrapper classes.

> All objectives related to AWT (there will be no questions on GUI programming.
> All objectives related to I/O.

> Questions on the Assertion mechanism will be on the exam (you must know how to appropriately use assertions (i.e. not just how, but when) and you must know the command-line switches for both compiling and running with assertions enabled). //要知道如何打開命令行方式下Assertions的開關，這個在中文書中有錯誤，（默認情況下Assertion是關閉的，打開爲 參數-en）
