Program 1: Sort the Elements of an Array in Descending Order In this approach, we will see how to use loops to sort an array in descending order. We can sort the array using manual sorting like using for loops. What we can do is use two for loops, one to traverse the array from t...
Java program to sort an array in descending orderimport java.util.Scanner; public class ExSortInDescending { public static void main(String[] args) { int n, temp; //scanner class object creation Scanner s = new Scanner(System.in); //input total number of elements System.out.print("Enter...
Java program to sort an array of integers in ascending order usingArrays.sort()method. //Unsorted arrayInteger[]numbers=newInteger[]{15,11,...};//Sort the arrayArrays.sort(numbers); 2.2. Descending Order Java providesCollections.reverseOrder()comparatorto reverse the default sorting behavior in...
1. Write a Java program to sort an array of given integers using the Quick sort algorithm. Quick sort is a comparison sort, meaning it can sort items of any type for which a "less-than" relation (formally, a total order) is defined. Click me to see the solution ...
You want to sort an array that is hard coded and not input during runtime, right? It should be simpler doing it hard coded. Once you have your array, perform a bubble sort or insertion sort on it. Those are simple sorting algorithms that are decently efficient for small...

[ArraySorter.java] public class ArraySorter { /* ** Sort in the same array */ public static void sort(Object[] a, Comparer comparer) { sort(a, null, 0, a.length - 1, true, comparer); } /* ** Sort a and b, using a as the reference ...
In the above program, we begin with an unsorted array, e.g.,array = {64, 34, 25, 12, 22, 11, 90}, and then call theselectionSortmethod. The algorithm utilizes an outerforloop to iterate through each array element. Within this loop,minIndexis set to the current indexi. In the in...
