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() ...

Object[] a=this.toArray();// 这个方法很简单,就是调用Arrays中的sort方法进行排序Arrays.sort(a, (Comparator) c); ListIterator<E> i =this.listIterator();for(Object e : a) { i.next(); i.set((E) e); } } 进入Arrays.sort()方法 ...
// Check if the array is nearly sorted for (int k = left; k < right; run[count] = k) { if (a[k] < a[k + 1]) { // ascending while (++k <= right && a[k - 1] <= a[k]); } else if (a[k] > a[k + 1]) { // descending ...
The integers are sorted in ascending and descending orders. The data is sorted in-place; i.e. the original list is modified. $ java Main.java [-4, -2, -1, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8] [8, 7, 6, 5, 4, 3, 2, 1, 0, -1, -1, -2, -4] ...
By combining sort() and reverse(), you can sort an array in descending order:Example const fruits = ["Banana", "Orange", "Apple", "Mango"]; fruits.sort(); fruits.reverse(); Try it Yourself » JavaScript Array toSorted() Method...
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...
Sort numbers in descending order: // Create an Array constpoints = [40,100,1,5,25,10]; // Sort the Array points.sort(function(a, b){returnb-a}); Try it Yourself » Find the lowest value: // Create an Array constpoints = [40,100,1,5,25,10]; ...
