The Java Heap is a memory area used by the Java Virtual Machine (JVM) to allocate memory to Java applications. It is divided into several regions, including the Eden Space, Survivor Spaces, and Tenured Space. The size and behavior of each region can be managed and tuned using various JVM arguments.
