按指定格式拼接字符练习

public class demo13{
    public static void main(String[] args) {
        int[] intArray = {1,2,3,4};
        String str = pingJieZiFuChuan(intArray);
        System.out.println(str);
    }
    public static String pingJieZiFuChuan(int[] intArray)
    {
        String str = "[";
        for (int i = 0; i < intArray.length; i++) {

            if(i == intArray.length - 1)
            {
                str += "word" + intArray[i] + "]";
            }else{
                str += "word" + intArray[i] +"#";
            }
        }
        return str;
    }
}
