I haven't seen Java for a long time, and the next week Java will start. I borrowed this JBIULD9 book on the weekend, but I didn't turn a few pages. I don't know what to learn from SQLPlus all day. It feels that it is not a subject of zero fragmented small things all day. cough. . . Do you have this wasteland in this weekend? Don't be willing to be unwilling, but it is still very helpless. I made a few IQ tests. It is said that I am a Visual Mathematician, an expert in Spotting Patterns - Both in Pictures and In Numbers, and the Right Job for you will allow you to be: Creative and analytical, What is Your TRUE Talent Is Spatial Ability. But even this is, I still don't know what to do this and Java's use of Java, so I still depressed.
