Perf4J and Object Creation/Destroy

Posted by & filed under , , , .

If at any point in your coding life you had to measure some component performance, chances are that you came across Perf4J at some point. To quote from their own website: Perf4J is to System.currentTimeMillis() as log4j is to System.out.println() There are of course other ways to measure timings of components execution, however, I found […]

Checking the Memory Quota

Posted by & filed under , .

This is somehow similar to the one above, except that this time an attacker can exploit the memory quota. This quota defines how much memory a user process can allocate at a time. If there is no capping on this value, a user process can try to allocate all the memory available in the system […]

StringBuilder — Memory Consumption

Posted by & filed under , .

You have seen probably my initial post about creating StringBuilder’s in Java — and the continuation of it which looked at timings involved. As I promised, I have finally had some time to look at the memory consumption involved in using the 2 ways of creating a StringBuilder in Java. I have used a code […]

Creating StringBuilder in Java

Posted by & filed under , , .

I wrote in my previous post about StringBuilder’s in Java, and I felt I should provide some measurements around the whole discussion. So I put together some quick and dirty code which is good enough for a comparison of the 2 ways of creating a StringBuilder — bear in mind I said “comparison”, as such […]

About Data Comparison in Java

If you have been involved in some coding (Java or otherwise) more than likely at some point you had to deal with the situation where you have to compare some data — for the purpose of sorting items in a list, of validating input, or many of the many other situations that require it. And […]
