Understanding OutOfMemoryError in Java | Java Exception Handling

In this Java tutorial, we'll explore one of the most common runtime exceptions encountered by Java developers: OutOfMemoryError.

OutOfMemoryError occurs when the Java Virtual Machine (JVM) runs out of memory while executing a Java application. This error typically indicates that the application has exhausted all available memory allocated to it.

In this video, we'll cover:
1. An in-depth explanation of what OutOfMemoryError is and why it occurs in Java applications.
2. Common causes of OutOfMemoryError, such as excessive object creation, memory leaks, and insufficient heap space.
3. Different types of OutOfMemoryError, including Heap Space, PermGen Space, and Metaspace errors, and their characteristics.
4. Strategies for diagnosing and troubleshooting OutOfMemoryError in Java applications, including memory profiling tools and JVM heap dump analysis.
5. Best practices for preventing OutOfMemoryError, such as optimizing memory usage, properly managing resources, and tuning JVM memory settings.

By understanding the causes and implications of OutOfMemoryError, Java developers can take proactive measures to write more robust and memory-efficient applications.

I am not crazy about using the term "may not" where we say "a method may not declare such errors in its throw clause". Better to just say "should not". Your silly code will still compile if you do, I just checked in Java 14. Other programmers will think you are incompetent or just weird, or wonder if you had some special esoteric knowledge they are unaware of, so you should not do it. The term "may or may not" is just fine to mean "maybe something, maybe not something" but when the words "may not" are by themselves many English-speakers will think that you are announcing a Prohibition, e. g. do not declare your interface final or it won't compile (do not, it won't). "Might not" let's the reader or viewer know that something they expected to be true might not be true. A method might or might not declare such Errors in its throws clause (throws not throw). Stronger yet, it *should not* declare such errors in its throws clause, because, that is just weird. The whole JVM is spiraling to the ground at the point you get such an error....there's no reason to try to catch them.
