Heap and Stack memory allocation in java, JAVA Programming

Assignment Help:

Each time an object is started in Java it goes into the area of memory named as heap. The primitive variables like double and int are allocated in the stack, if they are local instances and in the heap if they are member variables. In Java functions and local variables are pushed into stack when a function is called and stack pointer is decremented when a method invoke is finished. In a multi-threaded application each thread may have its own stack but will share the similar heap. That is why care could be taken in your code to avoid any concurrent access concern in the heap space. The stack is thread-safe because each and every thread will have its own stack with say 1MB RAM allocated for each thread but the heap is not thread-safe unless protected with synchronization through your code. The stack space may be increased with the -Xss option.

All Java functions are automatically re-entrant. It states that various threads can be executing the same method at once, each with its own copy of the local instance. A Java method can call itself without using any special declarations. That is known as a recursive method call. Provided enough stack space, recursive method calls are completely perfect and valid in Java though it is tough to debug
