We’ll consider a lapsed listener problem as an example of a memory leak. This is an excellent way to learn about memory allocation in Java and garbage collection. Let’s create an application to send a random movie quote to the users who logged in and subscribed to our service. This app...

For reference, the 3 most common parameters used to change the memory (heap) allocation are: Xms- the minimum size of the heap Xmx- the maximum size of the heap XX:MaxPermSize- the maximum size of PermGen (this is not used in Java 8 and above) Need advice regarding how m...
Stack memory size is very less when compared to Heap memory. Because of simplicity in memory allocation (LIFO), stack memory is very fast when compared to heap memory.
If you see this error message and the top frame of your stack trace is a native method, then that native method has encountered an allocation failure. The difference between this message and the previous is that the Java memory allocation failure was detected in a JNI or native method rather...

Businesses that provide external services often bring more active memory allocation actions (such as creating new objects and starting execution threads). These operations need to open up memory space, so online businesses often consume more memory. The higher the traffic peak, the more memory consum...
