Yesterday, during the conversation, Java mentioned Java, I have long known that now Java's fire violentness, but I didn't expect myself to face this issue. I like C, go to C , I can't talk about it, it is just skilled in other words. Nowadays, I have been looking for work, helpless, can only be prepared to use winter vacation time to learn Java. During this time, I have lost a lot of learning new technologies, but I have received a lot of things for professional courses (3 doors in my professional class: DS, OS, CS) have always thought that there is no such class. Large use, although the scores are not low, they have never appreciated the essentials. Now, for example, give me a simple C program, at least clearly understand the compilation process of the C compiler, it can generally write the disassembly code, which is greatly advantageous. Maybe this is a verification that "there is no need to have". Sometimes I always want to do my own compiler, but my ability is shallow, patience also needs to practice exercise. I sent my classmates to the reading room of the library, and I found a "Sleepless in Java" of Cai Xueqi inadvertently. It is a set of prose. Turning, I feel very interesting, the content of the book is the author's online article. It is also a bit of emotion that is hot in reading.
