I've been working with NetBeans for a Java class and I've noticed it uses a lot of memory—much more than Visual Studio did in my previous classes. When I was using Visual Studio for basic console applications, it would use around 300-400 MB, maybe a gig during builds or debugging. But with NetBeans, it starts at a gig and just climbs from there. Is this high memory usage typical for IDEs when developing in Java, or is it specific to NetBeans?

Yes, high memory usage is pretty standard for Java IDEs. It’s not just NetBeans; even heavyweights like IntelliJ use a lot of RAM. Java runs on a JVM, which adds some overhead since you’re essentially running another program to execute your code. But on the flip side, RAM is relatively inexpensive nowadays, especially compared to the cost of dealing with bugs in other languages like C++.
Definitely. When it comes to business applications, Java running on robust servers can rely on terabytes of RAM, so a few gigs on your development machine doesn’t matter much. IDEs are built to support extensive projects, and with today's RAM prices, it's usually not a big deal if they consume a lot of memory.
