Usually, the memory layout of run-time data areas is not part of the JVM specification and is left to thediscretion of the implementor. Therefore, each JVM implementation may have a different strategy to layout objects and arrays in memory. In this tutorial, we’re focusing on one specific ...

Memory layout is as below. I will talk about the stack in the next session. The diagram below shows the memory layout of a typical C’s process. The process load segments (corresponding to ” text ” and ” data ” in the diagram) at the process’s base address. The main stack is ...

In this quick tutorial, we’re going to see how to find the memory address of objects in Java. Before going any further, it’s worth mentioning that the memory layout of runtime data areas is not part of the JVM specification and is left to thediscretion of the implementor. Therefore, ...
As mentioned above, the concept of heap space exists both in Linux process memory layout and JVM memory layout but differs immensely. Therefore, it is easy for us to confuse one with the other. The Java heap is smaller in scope than the heap of a Linux process. It is a segment of log...
The Java virtual memory map is a representation of the memory layout used by a Java process. It consists of several regions, each serving a specific purpose. Let’s dive into the different regions and their functions. Heap The heap is the region where objects and their instance variables are...
Now we know how to calculate the memory used by any instance of a class that extends Object directly. One practical example is the java.lang.Boolean class. Here is its memory layout: [HEADER: 8 bytes] 8 [value: 1 byte ] 9 [padding: 7 bytes] 16 ...
This includes native allocations or runtime metadata, which the tool cannot identify when collecting this data due to Address Space Layout Randomization. Private Dirty is unknown RAM dedicated to only your application. ### procrank One alternative to dumpsys is procrank, another useful tool that...
