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...
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 ...
This Integer.compare() is a new method added to Java 8. Since we are using Comparator of String, the compiler is also smart enough to infer the types of a and b, which is, of course, String.If you are interested, please see Java 8 New Features in Simple Way to learn more about ...
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’...
The values are inserted in the of function to form a stream. In the chain series, the sorted function gets called. The function takes a Comparator instance to arrange the keys in a sequence depending on the order defined. The function comparingByKey returns the comparator that compares the ...
( 50, new Comparator<Recognition>() { @Override public int compare(final Recognition lhs, final Recognition rhs) { // Intentionally reversed to put high confidence at the head of the queue. return Float.compare(rhs.getConfidence(), lhs.getConfidence()); } }); for (int i = 0; i < ...
In this tutorial, we've gone over how to sort a Java HashMap by Key. We've initially used a TreeMap to sort and maintain the order of the sorted entries, both using the default and custom comparator. Then, we've Java 8 Streams with the LinkedHashMap class to achieve this functionalit...
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…
