How much RAM do you need on a laptop to work with IDEA Java?

Question

Java

Hello.
I want to buy myself a new laptop and install IDEA there to work with a Java project. Tell me, how much you need to have a minimum of RAM so that everything works more or less adequately?

Answer 1

Everyone has their own definition of adequacy.
Project sizes also vary.
The presence of the absence of an SSD is also important (this is noticeable on a small RAM).
And the processor - on a small RAM it is noticeable.
I wouldn't do less than 4.
All the same, you constantly need a browser to work, in order to climb for advice on StackOverflow, etc.
All the same, from time to time the program needs to be run for debugging.
Better in general 8, it will be more magical.
But if the software is heavy, then https://vc.ru/p/xored-vs-adamovsky
Here a person needed 128 G.
And on average, for development, if the developer is not tightly nailed to the budget, as a rule, 16 G.
But this is already quite well.

Answer 2

1. The processor must be quad-core - you can use the fifth generation instead of 6, i5 5gen quad-core is better than i7 6gen dual-core, don't be fooled by modern slides and other bits. my old pc with i5 3gen does almost everything on my laptop i7 6gen (virtualization is noticeably worse though)
2. memory from 12, 16 is better
3. ssd is a must

Answer 3

First you need to decide which projects you plan to develop, and what environment is required for development and testing. From my own experience, I can say that 8GB is a sufficient minimum (even without an SSD) for development. In any case, when working with Linux Mint, I did not notice problems when launching 4-5 developed enterprise projects with a running IDE (be it NetBeans or IDEA), Java Mission Control and a browser one time.
The browser, by the way, will not eat a lot of resources if you do not open several dozen tabs.
And yes, the SSD is a very desirable acquisition, it really speeds up the work in the IDE.

Answer 4

Dual-core 3805U, 4 gigabytes of memory, ssdshka , normal flight is not the first year, I still see no reason to update
Do not listen to these guys who fill in about "at least 8"
small projects), then you can safely do anything. Unless you gobble up all the memory with your own software, of course. Well, buying more memory and inserting it, if necessary, is a matter of one day and a couple of kopecks, while laptops for extra 4GB often have a disproportionate markup
