Java 8 streams provide us with one-line solutions to most of the problems and at the same time, the code looks cleaner. Stream’sflatMap()method can be used to get the elements of two or more lists in a single stream, and then collect stream elements to anArrayList. UsingStreamis reco...
That means the stream will have only two elements, which are the two collections. After which, we use flatMap to merge them to create combined steam of their elements. Finally, we are collecting the stream elements together in anArrayList....
Sometimes it will be great to have handyutilityready which combines two or multipleJSONObjects. Here is simple Java example which shows the same. packagecrunchify.com.tutorials; importorg.json.JSONException; importorg.json.JSONObject; /** * @author Crunchify.com * Program: How to M...
In this example, we have a list of integers that we want to sort in ascending order. We use theCollections.sort()method to sort the list, and then print the sorted list to the console. The output shows the list sorted in ascending order. This is a basic way to sort a list in Jav...
Learn tocompare two ArrayListin Java to find if they contain equal elements. If both lists are unequal, we will find thedifference between the lists. We will also learn to find common as well as different items in each list. Note that the difference between two lists is equal to a third...
