The speed of the blog finally returned to normal, a few days did not put some good things in their blog. I always want to be too sorry to have been concerned about my blog readers. I thought this evening can have time for everyone to find some good information, but a annoying problem entangled me one night. Oh...... Don't think much of it, it's a Java problem. After a busy night to finally get the problem done, not only do I feel a sense of achievement, learn something, the most important thing is that I really found the value of a book-"Java depth adventure." To tell the truth, I have read this book several times, without looking at it, there will be a new harvest. Today's problems are looking for information everywhere, but in the end the Java depth adventure helped me solve the problem. Oh...... If "Thinking in Java" is a necessary theoretical book for Java learners, then I think this book should be the necessary practical reference books. Oh...... And it is not expensive, it is very recommended to buy a copy. Oh, just say so much. Sen Wang seems to be a good writer. (:) I am not blowing oh ha ... )。
