First blog (independent of technology)
First blog I do not know where to start, there is the idea of a blog is because you want to record their own learning and summarize the history of Java, in July 2019 21, the time of writing this blog is junior summer vacation.
Since the university is software engineering, so in the future want to engage in IT industry, freshman learning a language is a C-based, junior learn a language is Java, follow-up feeling in the school also learned a lot about other computer-related knowledge, but we do not learn how to start summer vacation Fortunately, mainly to learn Java. University learned mostly on their own self-study is not much hope there is not too late senior year trying it. What began in the school feel their own school computer network technology, UML, compiler theory and so on. Began to think completely useless, but later found things to learn in college is very important, simply put inside the university you practice internal strength, the effect is not obvious, and the subsequent ability to learn language code is the external work is to show it skills If University school of internal strength is good, the follow-up to learn personally think (do not spray personal understanding) will be very easy.
Let me talk about the first day of learning Java, mainly the knowledge of the computer:
- Software: invisible, intangible. Hardware: visible and tangible. These are also simple answer on books.
- Compiled language: specific format, logic design software to complete specific symbol.
- Assembly: all kinds of data, instructions, text, memory address, written in simple English words.
- High-level language: what I want to learn a language is one of them (Java) various packaging operations, to complete a specific function using a specific format.
Learn a few commands:
- Window + r, into the input cmd
- shift + right mouse button, open a command window here
- dir lists all files in the directory name
- To switch cd directory
- rd directory to be deleted
- md + file name to create a folder
- Name del + delete folders
The first day insist, accumulation, come on.
