Sorts the specified array of objects into ascending order, according to the natural ordering of its elements. All elements in the array must implement the Comparable interface. Furthermore, all elements in the array must be mutually comparable (that is, e1.compareTo(e2) must not throw a Class...
Learn to sort a JavaSet,ListandMapof primitive types and custom objects using Comparator, Comparable and new lambda expressions. We will learn to sort in ascending and descending order as well. Quick Reference //Sorting an arrayArrays.sort(arrayOfItems);Arrays.sort(arrayOfItems,Collections.reverse...

The opposite of sorting, rearranging a sequence of elements in a random or meaningless order, is called shuffling. Data can be sorted alphabetically or numerically. The sort key specifies the criteria used to do the sorting. It is possible to sort objects by multiple keys. For instance, when ...
In Java, to sort objects based on their properties, we use a comparable or comparator interface. Let’s see how can we use them to sort an list of objects. Method 1: Using Comparable Interface Java has an inbuiltComparableinterface, which when implemented by a class, its objects could be...

Java Copy In this example, we’ve created a customComparatorthat comparesPersonobjects based on their names. We then pass thisComparatorto theCollections.sort()method to sort our list of people. The output shows the names of the people in alphabetical order. ...
