In one of the previous examples, we covered how to sort an ArrayList in ascending order. In this post, you will learn how to sort ArrayList in descending order in Java. We will explore the following ways: Using the sort() method Using the Collections.sort() and Collections.reverse() ...
Learn to sort Java ArrayList in ascending and descending order using ArrayList.sort(), Collections.sort(), Comparator interface and Java 8 Streams.
要对ArrayList进行排序,请使用Collections.sort()。 List<String> fruits = new ArrayList<String>(); fruits.add("Pineapple"); fruits.add("Apple"); fruits.add("Orange"); fruits.add("Banana"); Collections.sort(fruits); int i=0; for(String temp: fruits){ System.out.println("fruits " + ++i...
* The implementation takes equal advantage of ascending and * descending order in its input array, and can take advantage of * ascending and descending order in different parts of the same * input array. It is well-suited to merging two or more sorted arrays: * simply concatenate the arrays...

java System.out.println("Sorted list in descending order:"); for (int number : numbers) { System.out.println(number); } 将以上代码片段组合起来,你将得到一个完整的Java程序,用于对一个整数列表进行降序排序: java import java.util.Collections; import java.util.List; import java.util.ArrayList;...
importjava.util.ArrayList;importjava.util.List;publicclassExampleList{publicstaticvoidmain(String[]args){List<Integer>numbers=newArrayList<>();numbers.add(5);numbers.add(3);numbers.add(8);numbers.add(1);System.out.println("Original list: "+numbers);}} ...
In Java, thesort()method can be customized to perform sorting in reverse order using theComparatorinterface. Example: Sorting in Descending Order importjava.util.ArrayList;importjava.util.Collections;importjava.util.Comparator;classMain{publicstaticvoidmain(String[] args){// Creating an array listArr...
import java.util.Comparator; public class DescendingComparator implements Comparator<Integer> { @Override public int compare(Integer o1, Integer o2) { return o2 - o1; } } ``` 然后,在 main() 方法中使用这个降序比较器对 ArrayList 进行排序: ```java umbers.sort(new DescendingComparator()); ``...
In the following code example, we use the ascending() method to sort the sample collection by the _id field: import static com.mongodb.client.model.Sorts.ascending; // <MongoCollection setup code here> List<Document> results = new ArrayList<>(); collection.find().sort(ascending("_id"))...
