Mar 15, 2024 · In Java, sorting an array consists of arranging the elements in a particular order, such as ascending or descending. This can be achieved using various algorithms like Bubble Sort, Selection Sort, or Insertion Sort. A menu-driven program allows users to select the desired sorting method dynamically.

Apr 8, 2025 · To sort an array of strings in descending alphabetical order, the Arrays.sort () method combined with Collections.reverseOrder () method and it arranges the strings from Z to A based on lexicographical order. We can sort an array of objects by defining custom sorting logic with the help of using the Comparator interface. Explanation:

Jan 31, 2025 · Program to Implement Quick Sort in Java. Complexity of the above Program: Auxiliary Space: O (N) in the worst case and O (Log n) on average. Mainly the extra space required is for recursion call stack and the worst case happens when one part is always empty. Please refer complete article on QuickSort for more details!

You can use the sort() method, found in java.util.Arrays, to sort an array: Example import java.util.Arrays; public class Main { public static void main(String[] args) { String[] cars = {"Volvo", "BMW", "Tesla", "Ford", "Fiat", "Mazda", "Audi"}; Arrays.sort(cars); for (String i : cars) { System.out.println(i); } } }

Sorting is a fundamental concept in Java programming and is frequently asked in technical interviews. It helps in organizing data efficiently, making search and retrieval operations faster.
