ArrayList numbers = new ArrayList(); TreeSet ts = new TreeSet(numbers); numbers = new ArrayList(ts); System.out.println("\nThe numbers in ascending order are:"); for(int i=0; i System.out.print(numbers.get(i).intValue()+" "); System.out.println("\nThe numbers in descending ord...
32)How to sort ArrayList in descending order? To sort the ArrayList in descending order, we can use the reverseOrder method of Collections class. Consider the following example. importjava.util.ArrayList; importjava.util.Collection; importjava.util.Collections; ...
The direction of your sort can either be ascending or descending. An ascending sort orders your results from smallest to largest. A descending sort orders your results from largest to smallest. Here are some examples of data sorted in ascending order: Numbers: 1, 2, 3, 43, 43, 55, 120 ...

内置的解决方案名为sort(),它在java.util.Arrays类中有许多不同的风格(15 种以上的风格)。 在sort()方法的背后,有一个性能良好的快速排序类型的排序算法,称为双轴快速排序。 假设我们需要按自然顺序对整数数组进行排序(原始类型int。为此,我们可以依赖于Arrays.sort(int[] a),如下例所示: 代码语言:javascript ...
In order to overcome the problem we need to follow the steps below: We can make the variable private or protected. Use public accessor methods such as set<property> and get<property>. So that the above code can be modified as: public class Addition(){private int a = 5; //Here the ...
Like Tree set, we can construct a sort order with the constructor. Example: public class Fruit{ public static void main(String[ ]args){ TreeMap&lt;Sting,String&gt; names =new TreeMap&lt;String,String&gt;( ); ...
