Java:字符串的分割的两种方法 1.split(); 语法格式:str.split(String sign) (sign:分割字符串的分隔符,也可以用正则表达式) 例子: 结果: 2.str.split(String sign,int limit) (limit:限制分割的份数) 结果: !!!注意: 没有统一的对字符串进行分割的符号。如果想定义多个分割符,可使用符号“|”。如:“ ...
Concatenate any number of strings. The string whose method is called is inserted in between each given string. The result is returned as a new string. Example: '.'.join(['ab', 'pq', 'rs']) -> 'ab.pq.rs' """pass 看了构造就知道函数内需要传入可迭代对象,所以我们先传入一个列表演示...
The limit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array. If the limit n is greater than zero then the pattern will be applied at most n - 1 times, the array's length will be no greater than n, ...
