What is Java heap space and how can I manage it?
Java heap space is the memory allocated to Java applications for dynamic memory allocation. You can manage it by adjusting the JVM parameters like -Xms (initial heap size) and -Xmx (maximum heap size).
What happens if the heap space is full?
If the heap space is full, the Java application will throw an OutOfMemoryError, indicating that it cannot allocate more memory.
How can I monitor the heap space usage?
You can monitor heap space usage using tools like VisualVM, JConsole, or by enabling garbage collection logging in the JVM.
What are some common causes of heap space issues?
Common causes include memory leaks, excessive object creation, and not properly releasing resources.
