Memory Types In Java

Why is this necessary?

To avoid errors. Beginners in programming often encounter situations where the code compiles incorrectly and produces numerous errors. Let's take a look at the main errors you might encounter at the beginning of your developer journey:

• Syntax Error: this happens when there’s a mistake in how the code is written, like missing punctuation or typing a word incorrectly;
• StackOverflow: this means that you have overflowed your stack memory. This occurs when too much memory is used for quick-access data. It happens when too many objects are created;
• OutOfMemoryError: this error indicates that you have exceeded your heap memory. This means your program has used more memory than what’s available for storing data. It’s harder to reach this point, but it can happen if too much data is being stored.

Knowing about these three most common errors at the beginning, you'll be able to learn Java faster and won't be stuck when one of these errors pops up. Furthermore, in the future, you'll become an excellent embedded programmer, and you'll need to optimize memory and resource usage to make your program run much faster.
