Previously, you saw how a multithreaded system brings complexities with it and how can we solve it using synchronization. Now let’s see how threads can talk to each other.
I would suggest those who haven’t read that Part 1 yet, please go through it to understand the next story without any suspense.
However, these are the key concepts that we learned last time.
This is my story about learning concurrency. I have divided it into parts and this one is more focused on the problems concurrency and multithreaded system brings with them.
I kept hearing these terms parallelism and concurrency. Read their definitions, didn’t make any sense to me. It was like concurrency is a problem and parallelism is a solution to it or vice versa couldn’t recall it every time.
I searched a lot again and then I finally got to this fine article written by Jakob Jenkovs.
It cleared many things, then I saw an image on the internet which gave…
I wanted to see how garbage collections work. but all i can find was theory and theory. Thus thought to try it out with a very basic program to see it practically.
Some basic information that one should know.
1 Eden Space : All the new objects that are created goes to this part of heap
2 Survivor Spaces (S0/S1) : After minor GC reachable object from the Eden space and from one part (S0/S1) of the survivor space is transferred to another part of survivor space (S0/S1). And with this the age of each surviving object is incremented.
