We can also easily carry out other operations like accessing, storing, etc. Sorting of data is useful as we can search for data more efficiently and quickly. Q #4) What is the use of Sorting in Java?Īnswer: Sorting is a technique of arranging data in a particular order. Comparator interface is mostly used during the sorting of objects using the sort method. Q #2) Which Sorting technique is used in Arrays sort in Java?Īnswer: Arrays use dual-pivot Quicksort for primitive data types and Mergesort for sorting objects.Īnswer: Comparator interface is a part of the java.util package and is used to arrange the user-defined objects. Frequently Asked QuestionsĪnswer: Sorting refers to arranging data in order either alphabetically or numerically. The output of the program shows a sorted array of strings in both ascending as well as descending order. ("Array sorted in descending order : \n%s\n\n", ("Array sorted in ascending order: \n%s\n\n",Īrrays.sort(str_Array, Collections.reverseOrder()) ("Original Array: \n%s\n\n", Arrays.toString(str_Array)) You can use a temporary variable for the swapping of elements. In the body, you compare the adjacent elements and swap if they are not in order. What you can do is use two for loops, one to traverse the array from the starting and another for loop inside the outer one to traverse the next element. You can sort the array using manual sorting like using for loops. Let’s explore both these methods in detail. This is a direct sorting method and you can sort an array with just one method call. Using The Sort method: The Arrays class of ‘java.util’ package provides the sort method that takes an array as an argument and sorts the array.Using For Loops: You can use for loops to traverse the array and compare adjacent elements while traversing and putting them in order. ![]() Java provides the following methods to sort the arrays. Sort String Array In Alphabetical Order.
