experience about computer language several years ago, when i was as a high school student, i learnt and only knew about a language, pascal. then several next years after that (about several months ago), when i entranced as an university student, i began to be introduced about c (and also little c++). presently, the language lesson has evolved to be java, an oop language. so i can begin to practice about java "fluently" (have not anything difficulty to practice it). so the growing about my "language" ability is quite extraordinary, because i can do it quite rapidly. thx god about your helping, although it can also be gained by my effort-self :)
