and limited memory plus processes that use a lot of RAM can cause a situation where the kernel goes out of memory (OOM). In this state Linux activates an OOM killer kernel process that attempts to recover
This is a basic way to sort a list in Java, but there’s much more to learn about sorting lists, especially when dealing with custom objects or when you want to sort in a different order. Continue reading for a more detailed understanding and advanced usage scenarios. Table of Contents[hi...
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 ...
To measure time elapsed in Java, you can use the System.currentTimeMillis() method to get the current time in milliseconds, then subtract the start time from the end time to get the elapsed time.
2. Memory use Memory usage is also an important application performance metric. It should be noted that high memory use, memory leaks or insufficient memory will adversely affect application performance and scalability. High memory usage indicates high resource consumption in the server. Whe...
