The process works by comparing the data elements, hence, defining the new positions. There are various types of sort algorithms defined in Java that are useful based on the complexity of the structure. Below is the code block that defines overriding the comparator interface to give our ...
As I said before using lambdas to implement a Comparator is a good way to learn how lambda expression works in Java. Since lambda expression in Java is SAM type (Single Abstract Method) you can use it with any interface which got just one method like Comparator, Comparable, Runnable, Callab...

Objectcloningin Java is not an easy concept. I took a long time to understand cloning in Java. It seems simple; use the Cloneable interface and override clone() method. But wait, there is much more to tell and ask in an interview. e.g. How clone() method works? What is shallow cop...

WhileCollections.sort()andComparatorare versatile and powerful, Java offers other methods and classes for sorting lists. Let’s explore some of these alternatives. UsingArrays.sort() TheArrays.sort()method is another way to sort arrays in Java. It works similarly toCollections.sort(), but it’...
How does a UVM Comparator works? For example if I pass 4 transactions on a comparator’s before_export, let’s say tr0, tr1, tr2, and tr3, and then I pass 1 transaction to after_export. So to which expected transaction wi…
