Why can I register an OutOfMemory error in java?

Question

To register anything in a catch block, we need text that is a String object, but the JVM has already run out of memory. There are two possible reasons:

• The OutOfMemory error means empty space and the String object can be stored in the string pool.
• An OutOfMemory error means that less space is left, unlike a heap that is completely full, and you can use less space to store the line that needs to be registered.

Answer 1

A very broad question, but one simple answer: when implementing the JVM, you probably won't want to wait until you have 100% of your memory.
