In Java, we can sort a list in-place or we can return a new sorted list. default void sort(Comparator<? super E> c) TheList.sortmethod sorts the list according to the order induced by the specifiedComparator. The sort is stable. The method modifies the list in-place. Stream<T> sort...
下面是一个简单的例子,对一个包含字符串的List进行倒序排序: List<String>names=Arrays.asList("Alice","Bob","Charlie","David");Collections.sort(names,Comparator.reverseOrder());System.out.println(names); 1. 2. 3. 以上代码将会输出:[David, Charlie, Bob, Alice],即对List中的字符串按从大到小...
使用Collections.sort方法对List进行排序: 为了进行倒序排序,我们可以使用Collections.sort方法,并传入一个Comparator对象。 自定义一个Comparator来实现倒序排序: 我们可以使用Comparator.reverseOrder()方法创建一个比较器,该比较器会按照相反的顺序对元素进行比较。 java import java.util.ArrayList; import java.util....

Java version:1.8+ More Examples Example Use a lambda expression to sort a list in reverse alphabetical order: importjava.util.ArrayList;publicclassMain{publicstaticvoidmain(String[]args){ArrayList<String>cars=newArrayList<String>();cars.add("Volvo");cars.add("BMW");cars.add("Ford");cars.add...
MyList.stream().sorted((obj1,obj2)->obj1.getItem().getValue().compareTo(obj2.getItem().getValue())).forEach(System.out::println); Below is an example of a sorted stream in reverse order. importjava.util.*;publicclassStreamCompareToExample{// Main functionspublicstaticvoidmain(String[]...
Nest Java program sorts the list ofEmployeeobjects by their name; ArrayList<Employee>employees=methodReturnsUnsortedList();//Narutal order sortingCollections.sort(employees);//Reverse sortingCollections.sort(employees,Collections.reverseOrder());
publicstatic<T>voidsort(List<T> list,Comparator<?superT> c) 如果想采用其他方式进行排序,那么可将一个Comparator对象作为sort方法的第二个参数。当要进行逆序排序时,最简便的方法是将Collections.reverseOrder()作为第二个参数。 importjava.util.*;publicclassSort{publicstaticvoidmain(String[] args){...
In simple, using Comparator and Collection you can sort like below in reversal order using JAVA 8 import java.util.Comparator;; import java.util.stream.Collectors; Arrays.asList(files).stream() .sorted(Comparator.comparing(File::getLastModified).reversed()) .collect(Collectors.toList());...
