把数组[1,2,3]按照指定的格式拼接成字符串，比如说[word#word#word]的形式

public class Demo15Example {
    public static void main(String[] args) {
        int[] num = {1, 2, 3};
        String s = fromArrayToString(num);
        System.out.println("s==========="+s);
    }
    //拼接
    public static String fromArrayToString(int[] array) {
        String s = "[";
        for (int i = 0; i < array.length; i++) {
            if (i == array.length - 1) {
                s += "word" + array[i]+"]";
            } else {
                s += "word" + array[i] + "#";
            }
        }
        return s;
    }
