A data structure is a specialized format for organizing, processing, retrieving and storing data. There are several basic and advanced types of data structures, all designed to arrange data to suit a specific purpose. Data structures make it easy for users to access and work with the data they...
“A data structure is a way of organizing data in some fashion so that later on, it can be accessed, queried, or even updated easily and quickly” It is a collection of values. The values can have relationships among them and they can have functions applied to them. Besides, each one ...
The Java heap is the area of memory used to store objects instantiated by applications running on the JVM.When the JVM is started, heap memory is created and any objects in the heap can be shared between threads as long as the application is running. The size of the heap can vary, so ...
On the other hand,heapis an area of memory used fordynamic memory allocation. Blocks of memory are allocated and freed in this case in an arbitrary order. The pattern of allocation and size of blocks is not known until run time. Heap is usually being used by a program for many different...
How do I check whether an application is a system application? How do I capture the crash stack and implement the crash callback? How do I analyze the CPU usage of an application in running? How do I quickly read and analyze heap dump (memory), application memory usage, and maximum...
stack is a linear data structure and heap is a hierarchical data structure. stack memory will never become fragment but heap will be because blocks of memory are first allocated and then freed. stack accesses local variables only and heap allows you to access variables globally. ...

Starting from Java 8, theMetaspaceis the memory space that replaces the removed PermGen space. The implementation differs from the PermGen and this space of the heap is now automatically resized limiting the problems of going into out of memory in this region of the heap. The Metaspace memory...
