Java Learning Experience 03

Object-oriented feelings are different.

the Python 's impression is a graceful grammar, the impression of C is specific to the micro but cumbersome, and the sense of Java , so far, it graceful in the algorithm description, absorbed C language specific to the micro, but not cumbersome.

The use of classes is very quick (probably learned Javasript 's sake), and not much of a problem.

Last week, learned the new java this this I think it's like in classical Chinese "its" or "English" that ". In Classical Chinese, the meaning of "its" refers to its father, his mother and so on. In English, that refers to one of the preceding mentioned, which can be a sentence or a word , in particular, according to contextual to judge. Interestingly, you can't ask the machine to use contextual to judge the object of a reference like a human, so this The use of the method of sub-objects and methods.

in this week's study, also encountered some problems, the most prominent is the lack of learning resources. There are two aspects, one is the book to the grammar description is unclear, another problem is an example or code an example is not enough or is not very intuitive. When learning three "Device" methods, the constructor, the accessor is not too much of a problem, mainly the change, the problem of parameter change is not looked closely, may be wrapped in. Especially when learning static, I think it is not very intuitive, there is a positive and negative contrast, perhaps learn faster. There is a question of this, the book is not many examples of this, but also a few grammatical instructions, may need the guidance of teachers. Finally I want to say the efficiency problem, in writing code, although I spend a lot of time to thoroughly understand the grammar of the textbook, but in the writing of grammar, some difficult, reflect on, mainly on the concept of grammar inflexible, not flexible, scrutiny reason, in addition to lack of material, more is the lack of exercise, the lack of self-written program of exercise.
