python # 假设我们有一个包含整数的列表,并尝试使用 join() 方法将其连接成一个字符串 integer_list = [1, 2, 3, 4, 5] # 错误的做法:直接尝试使用 join() 方法,会抛出 TypeError # result = ''.join(integer_list) # 这会抛出 TypeError # 正确的做法:先将整数列表转换为字符串列表,然后使用 join...
Iterable<Integer> numbers = Arrays.asList(1, 2, 3, 4); String joinedNumbers = String.join("-", (Iterable<CharSequence>) numbers.stream().map(Object::toString).collect(Collectors.toList())); System.out.println(joinedNumbers); // 输出: 1-2-3-4 } } 注意:由于 String.join 的第二...
这里和StringUtils.join()有区别,参数顺序不一样,另外,StringUtils.join()可以传入Integer或者其他类型的集合或数组,而String.join()尽可以传入实现charSequence接口类型的集合或数组。 如果是字符串类型的集合或数组推荐使用String.join()。 代码如下: 代码语言:javascript ...
