若为降序排列,就倒着输出
import java.util.Scanner; import java.util.Arrays; public class Main { public static void main(String[] args) { Scanner input = new Scanner(System.in); int num = input.nextInt(); int array[] = new int[num]; for(int i=0;i<num;i++){ array[i] = input.nextInt(); } Arrays.sort(array); for(int n:array) System.out.print(n+" "); input.close(); } }
