  1. namdaemun jewelry wholesale This may be concerned from the operating system. The database of Windows is very expensive for the use of MSSQL. Specifically, hundreds of thousands of counts.
    unix are the most stable. After the operating system, I heard that it is a million -level (Money)

    So generally it has a certain scale but does not want to use linux MySQL data as the basis of the program as the basis for the basis of using Windows piracy. Support. But most of the systems used in general development are Windows, so there is a cross -platform problem of the program. Java just reads this problem. With the support of Java VM (Official language), program development (web) the final platform is UNIX, so Java can run between them.

    obviously the Java model actually simulates the realization of DLL realization. , But DLL can only run under the Windows platform. Java can only run on JVM. The principle is the same. I do n’t know if you can understand it. You must know that Sun is also doing the operating system. On the second line to do the Java virtual machine. But I found that this is very far away, so Microsoft also rewritten the idea of ​​DLL specifications. This is a great optimization in the 2.0 framework, but Microsoft has always been a monopoly company's goal of his goal. They are all selling his operating system. This is his ultimate goal, so he will not consider cross -platform issues, so Java has large advantages and benefits from our system, but you must know that the server system is finally going to move towards UNIX, so I need to spend money haha. But I did n’t explain the benefits of Java after saying so much,
    , but I need to know that Java has a promising future. However, the Java is not excellent in the development of the window. J2MS is more copied, and there are not many people who do it.

  2. john's wholesale jewelry Do you think you can use procedures with C or other languages ​​everywhere. Their applicability is narrower. What you are in contact with is PC Windows

  3. jewelry display wholesale nyc The reason why developers are developed are because of actual needs. Understand? If you do the requirements of the demand in advance, if you are not suitable for Java, they will not use Java.
    The operating system has many types, many application environments, and there are many applications. C and ASM are suitable for the underlying and hardware interface programs, and Java is suitable for cross -platform applications. Why is mobile game just Java's popular now? It is because of development costs, and development efficiency works. Because there are many types of mobile terminals, if you need to adapt to each model, if you make an adaptation for each machine, the high cost is not worth developing. However, KVM provides a layer of abstraction that allows developers to care about the bottom layer of the machine. This guarantees the development once. It only needs to make a small amount of changes to run well on different models. Similarly, if some CNC programs are made, Java is obviously unreasonable and efficiency cannot be guaranteed. In general, the chip selected is very clear, and it does not require large -scale transplants to other hardware. Therefore, it can be developed for specific hardware. Use C to improve development efficiency and use ASM to improve execution efficiency. Understand no
    It, most of the Java programs are not for stand -alone programs, but as server programs, mobile phone programs, etc. Therefore, the questions you ask are a bit bad.

  4. african costume jewelry wholesale Java network development, it is OK to install a virtual machine on the server. As long as the client has a browser, you can access the server. No software is not installed! Intersection Intersection

    Of course, network services can also be developed, but it is not open source. Only Microsoft provides it to use it. Some internal developers do not know at all, and they are developed with ready -made frameworks with J2EE. , Fast speed and low cost, which is also an important reason why J2EE is so popular

  5. wholesale acrylic jewelry display It's a lot, I guess your computer should visit the JSP page, but do you install JDK? It is estimated that it is not, but why can you still access it? The reason is that your machine does not read the Java code directly, but to read the HTML language converted by the server. All the browsers in this language are supported. No matter if you have or not? virtual machine. As the saying goes: one time, run everywhere! Ha ha

  6. gold jewelry wholesalers Answer: 99%of the world's browsers integrate Java virtual machines. The largest field of Java applications is web.
    Answer supplementary questions Support.
    2. Division of different desktop software has better languages ​​to edit. You can see most of the online games are C , and desktop management software is generally made by VB and other software. Web. Most of the company's Web server is on the Linux system.
    3. Java will continue. Although it is popular now.
