Program 2: Sort the elements of an Array in Descending Order In this approach, we will see how to use Arrays.sort() and Collections.reverseOrder() to sort an array in descending order. The Arrays class of ‘java.util’ package provides the sort method that takes an array as an argument...
AnArrayListis an ordered and unsorted collection of elements and is part of theJava Collections framework, similar to other classes such asLinkedListorHashSet.By default, elements added in theArrayListare stored in the order they are inserted. When we need to sort the elements in theArrayList, ...

First, in ascending order: int[] arr2 = ... Arrays.sort(arr2); Unfortunately, there's no way to sort in-place in descending order using a single-line operation. You will need to sort ascending first, then reverse the array: int[] arr2 = ... Arrays.sort(arr2); int size = ...
Collections.reverseOrder( new Comparator<String>() { public int compare(String o1, String o2) { if (o1.contains("_") && o2.contains("_")) { return compare(o21.substring(1), o2.substring(1)); } if (o2.contains("_")) { return 1; } if (o1.contains("_")) { return -1; ...
Write a Java program to sort the elements of the stack in descending order.Sample Solution:Java Code:import java.util.Scanner; public class Stack { private int[] arr; private int top; // Constructor to initialize the stack public Stack(int size) { arr = new int[size]; top = -1; }...
AMapin Java is an interface representing a collection of key-value pairs. While the data isn’t inherently ordered, sometimes we need to display or process it in a sorted manner. When sorting aMapin descending order by values, we need to consider the values associated with each key. ...
OrderByDescending操作符的功能与OrderBy操作符基本相同,二者只是排序的方式不同OrderBy是顺序排序,而OrderByDescending则是逆序排序。 例如, usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;namespaceConsoleApplication{classProgram{staticvoidMain(string[] args)...
