class a { public static void main(String[] args) { //将6插入到2后面 int[] a = {1,2,3,4,5,6}; //定义原数组 int[] b = new int[a.length+1]; //新建数组，长度+1 int index = 2; //定义插入点下标2 for(int i = 0; i < b.length; i++) { if (i < index) { //插入点之前 b[i] = a[i]; } else if (i == index) { //遇到插入点，将6插入 b[i] = 6; } else { //插入点之后 b[i] = a[i-1]; } } for (int i = 0; i < b.length; i++) { //遍历打印新数组 System.out.print(b[i]); } }}
