If you want to sort the original list in reverse order in-place, you can use thesort()method with thereverse=Trueparameter. This modifies the original list (technology) directly and sorts it in reverse order. Thereverse=Trueargument in thesort()method indicates that the sorting should be don...
当然可以自己编写合适的排序方法,但既然java包里有自带的Arrays.sort排序方法,在数组元素比较少的时候为何不用? Sorting an Array 1.数字排序int[] intArray =newint[] {4,1,3, -23}; Arrays.sort(intArray); 输出: [-23,1,3,4]2.字符串排序,先大写后小写 String[] strArray =newString[] {"z",...
2. SortArrayListin Natural (Ascending) Order Thesort()is part of theListinterface and has been implemented inArrayListclass since Java 8. It takes aComparatorinstance used for enforcing the sorting order. Note thatArrayList.sort()method does the in-place sorting i.e. it modifies the original...
We sort a list of objects by defining an external comparator object. Main.java import java.util.Comparator; import java.util.List; void main() { var cards = List.of( new Card(Rank.KING, Suit.DIAMONDS), new Card(Rank.FIVE, Suit.HEARTS), ...
fruits.reverse(); Try it Yourself » By combiningsort()andreverse(), you can sort an array in descending order: Example constfruits = ["Banana","Orange","Apple","Mango"]; fruits.sort(); fruits.reverse(); Try it Yourself »

As we all know, an array is a sequence of a bunch of elements in any given order whatsoever. Arrays are used to display information in that specific order only. As you can see in the image uploaded, the size of the array is entered first up. ...
