This article focuses on "how to configure a computer suitable for Java development", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor learn "how to configure a computer suitable for Java development".

Operating system Microsoft Windows 10 Professional Edition (64-bit) CPU (Intel) Intel (R) Core (TM) i5-10400 CPU @ 2.90GHz (2904 MHz) Motherboard Seven Rainbow CVN B460M GAMING PRO memory 32.00 GB (2667 MHz) main hard disk 500 GB (Samsung SSD 970 EVO Plus) CPU Core display Samsung C27R502 32-bit True Color 64Hz laptop or Desktop

Laptop or desktop is often the first option for you to buy a computer. The advantage of notebook is portability, whether it is for business or pleasure, you can put it in your bag and take it out. It allows you to write your code on the rooftop, in the grass, in the woods, in the SUV. The notebook occupies a small space, so you don't have to worry about not having enough space at home. You can put it anywhere at any time. Of course, this comes at the expense of some performance and scalability.

The advantage of desktop computer is performance and scalability, it is cost-effective, although the machine is relatively bulky, but in terms of performance, the same price, there is no way to compare notebooks. The disadvantage is that there is no portability, which can only keep you at home. The choice of notebook or desktop depends on your personal use scene and habit, and the ability to hold it both is the king.

How to choose a notebook here? First of all, let's look at the budget. Under the premise of meeting the budget, and then look at the mold heat dissipation, the mold is not good heat dissipation is not good, no matter how high configuration is useless, so more to search for relevant information.

The overall CPU capability of notebooks is weaker than that of desktops of the same model, so try to configure it as high as possible. Other indicators can be based on some references of desktops given below. Here's what I give you to develop Java.

Notebooks that do not jam should not be less than ¥6000, and the higher the better.

Below, whether you buy your own hardware to install the machine, or go to the computer city to let profiteers "pit", you should simply understand some knowledge.

AMD or Intel?

At present, Intel is a little more expensive than AMD. If there is no difference between likes and dislikes, choose a price that you can accept, but note that you have to use more than ¥1000 for the development of CPU, and the most intuitive way to look at performance is to look at money.

Minimum 16GB memory

For developers, especially for Java development, the memory must be larger, no less than 16GB. If you think about it, Java consumes more memory, and the IntelliJ IDEA we use is a large memory user, which easily takes up 2 gigabytes of memory. If you install and use database, Docker, Redis, MQ and other things on this machine, you need a lot of memory, so 16GB is a basic guarantee, the bigger the better.

Note that the current installed memory is not less than DDR4 (DDR5 is not yet on the market), and the frequency should not be less than 2666, please pay attention to screening when buying.

The motherboard should be adapted.

Choose the motherboard must be adapted with your other hardware, AMD CPU can only match the AMD platform motherboard, Intel CPU can only use the Intel platform motherboard; at the same time depends on your choice of memory frequency support, the maximum number of memory, DDR algebra; but also to see whether to support M.2 interface (which is to buy SSD solid-state consideration); and the motherboard size must be adapted to the chassis, buy these must be clear.

Hard drive must have SSD

At present, there are two configuration styles of hard disk, one is SSD solid state disk + mechanical hard drive, SSD is used to install system and commonly used software, mechanical disk is used as data disk, and the other is full SSD, which I am currently full SSD.

SSD solid state is the most intuitive hardware product to improve your experience. Load in seconds! At present, there are two kinds of SSD interfaces: SATA and M.2, SATA takes up more space, of course, the motherboard supports SATA; and M.2 is faster, but it needs the support of the motherboard. You can choose these two ways according to your needs.

Video cards are purchased on demand

Like CPU, graphics cards have a dispute between N cards and A cards. If you want to engage in machine learning, you can only buy NVIDIA stand-alone graphics cards, and it must be a high-end series with large memory. If you play some games occasionally, depending on your wallet, you can take a look at the latest graphics card ladder chart, and don't buy a "bright card" that is worse than your verification performance.

If you are only engaged in development, occasionally audio and video, verification is enough, you can save thousands of yuan.

Don't buy miscellaneous brands for power supply.

Power supply is a thing that is easy to be overlooked. What kind of power supply is appropriate? First of all, it is the price. The highest price you can afford must be good. But if you do not use a stand-alone graphics card but install a 1000W power supply is also a waste. In the case of no independent graphics card, generally 350W is enough, and the power consumption of the video card should be considered if there is an independent video card.

What about other indicators? Mainly in terms of conversion rate and protection mechanism, you don't want a shoddy power supply to destroy your computer. So the more features such as 80 PLUS, active PFC, and full module, the better. Generally speaking, do not buy some miscellaneous brand power supply, the price is recommended to choose more than ¥200.

More monitors, the better.

Do not flash + wide-angle, refresh rate can be on the 120hz IPS screen is the first choice. The anti-blue light display has an eye protection mode. It's better to be able to rise and fall, rotate, and get a bracket if you can. The more the number of monitors, the better, one to read the document, one to watch the code, and one to watch a movie. The computers you match are all designed to show you, so this is fundamental.

To install Win10 Professional Edition

If you use Windows development, it is recommended to use Win10 Professional Edition, professional version or above can use Docker. If you use MacOS, it is not recommended to hack Apple, the driver is too hard, and unstable, it is easy to collapse, save money to buy a Macbook Pro. You can also try Ubuntu, Deepin and other Linux systems, in fact, they simply engage in development is also good, that is, the software ecology is not friendly.

At this point, I believe you have a deeper understanding of "how to configure a computer suitable for Java development". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
