C/C++/Python (familiar and unfamiliar)
For this konjac, the two languages that are familiar and unfamiliar are simply talking nonsense from the perspective of an ordinary 0-1 (simply knowledgeable) scholar . As the two major compulsory languages in the freshman year, it can be said that there are countless pits. As a person with transparent logic ability, I was almost persuaded by the pointers at that time. The "suicidal" learning method of "all logic is not possible, algorithms are backed" accompanied me for a long time. The stalker-style learning, weirdly find that he has gradually fallen in love with the programming goblin. At this point, I think that computer language, as a carrier for humans to interact with computers, should understand it more from its overall framework, and then slowly improve their logical thinking ability in life. In many cases, they are not talented. , But it’s even more terrifying without talent or fighting spirit. As Mengxin, I don’t have much experience. It’s most important to be down-to-earth. Don’t blindly follow the brainwashing slogans of some crash courses now. Love will definitely result.
Java (Initial Brief Talk)
As the language with the top three users in the current programming environment, Java's superiority in the programming field is self-evident. When it comes to Java, there are three terms I have to mention, "JDK-Java Development Kit", "JVM-Java Virtual Machine" and "JRE-Java Runtime Environment". Among them, "JDK" is the core of the Java language, which contains a variety of tools for Java and a variety of libraries that support Java. The "JRE" and "JVM" are both important components in the "JDK" large tool library. The former is responsible for the interpretation and execution of the language. In order to simplify the programming workload, a large number of function libraries and classes are often used, and the existence of "JRE" can load these libraries and classes. The last "JVM", I think this is the main reason for the success of the Java language. Due to the existence of the built-in platform virtual machine, Java is no longer restricted by the device and has achieved the feat of "code once, execute everywhere".
I have learned that some official evaluations of Java are "Java is a pure object-oriented language, with good portability, excellent security, high performance and support for distributed programming languages." From these days It’s a waste of time to understand the general functions and background of Java . Java is not just a programming language, but a small integrated platform. It is like a "translator" between humans and computers. This is why it can be implemented across platforms. It does not require a machine to understand its language format. It can process the code language and submit it to the virtual machine for "translation", and finally become a machine code that can be recognized by various platform devices. Improve the efficiency of the code.
