Java 字符串Split方法的一个坑

 public static void main(String[] args) {
        String str = "ab|c||";
        String [] split = str.split("\\|");
        System.out.println(Arrays.toString(split));
    }

 public static void main(String[] args) {
        String str = "ab|c||";
        String [] split = str.split("\\|",-1);
        System.out.println(Arrays.toString(split));
    }
