The memory usage for one element is 4 bytes for an object reference; for a list of the memory usage of primitive types, see the page on Java data types. If the total memory usage of the array is not a multiple of 8 bytes, then the size is rounded up to the next mutlitple of 8...
Due to the fact that native heap is not part of a heap dump, the native memory cannot be directly analyzed using a Java memory profiler, so basically native memory usage remains as a mysterious black box whose content cannot be completely discovered. At this point is where the native ...
data types affect memory usage by determining the amount of memory allocated for storing values. for example, an integer typically uses less memory than a floating-point number. what is the difference between dynamic and static typing? in dynamic typing, data types are determined at runtime, ...

Heap is the memory space where java application objects are stored. Unfortunately the size of Heap is limited (by the -Xmx java command line option). When all of heap is used up, you are in deep trouble. So, it helps to understand how to measure Java heap usage, and that’s exactly...

Here’s the source code for a Java “memory eating” program I wrote. Its purpose is to consume all of the memory (RAM) on a PC by allocating 1 MB byte arrays until it runs out of RAM: import java.util.Vector; public class MemoryEater { public static void main(String[] args) { ...
Thread synchronization on Java can be done using monitor. Every Java object has a single monitor. The monitor can be owned by only one thread. For a thread to own a monitor that is owned by a different thread, it needs to wait in the wait queue until the other thread releases its moni...
Heap dump is a file of the memory that is used to check the objects and data in the Java memory. This file can be created by using thejmapcommand included in the JDK. While creating the file, the Java process stops. Therefore, do not create this file while the system is operating. ...
