Question

用java将数组元素{1,2,3,4,5}倒置后的顺序为{5,4,3,2,1}

Answer 1

public class Test { public int[] reverse(int[] a){ int[] b = new int[a.length]; int n = a.length - 1; for(int i = 0;i < a.length;i++){ b[n] = a[i]; n--; } return b; } public static void main(String[] args) { Test t = new Test(); int[] a = {1,2,3,4,5}; int[] b = t.reverse(a); for(int i = 0;i < b.length;i++) System.out.println(b[i]); } }
