What are the 5 memory allocation in Java?
Memory allocation in java occurs in two ways, mainly, stack and heap space.How the memory is allocated in Java?
Java objects reside in an area called the heap. The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.How does JVM allocate memory?
Stack memory gets automatically allocated and deallocated after the method completes its execution. Access to stack memory is fast as compared to heap memory. Whenever stack memory gets full, an exception called stack overflow exception is thrown by java. Stack memory is thread-safe as each thread has its stack memory.
