commonly used to split a string into an array of substrings based on a specified delimiter. However, there are cases where we may want to extract the content before a particular character in a string. This can be achieved by using thesplitmethod along with other string manipulation techniques...
看了下jdk里String类的public String[] split(String regex,int limit)方法,感觉平时不太会用这方法,以为在用正则表达式来拆分时候,如果匹配到的字符是最后一个字符时,会拆分出两个空字符串,例如"o"split("o",5) or "o"split("o",-2)时候 结果是"" "" 也就是下图中红框里的内容,所以平时一般都用spl...
我们通过以下的例子来分析一下split函数的原理。 publicvoidtest() { Stringstring="linux---abc-linux-"; splitStringWithLimit(string, -1); splitStringWithLimit(string,0); splitStringWithLimit(string,3); splitStringWithLimit(string,20); }publicvoidsplitStringWithLimit(Stringstring,intlimit) { ...
众所周知,我们可以将一个模式传递给String.split()方法,并获得一个由该模式拆分的字符串数组。 因此,我们的想法是,我们可以将输入字符串拆分为一个空格。然后,原始字符串中的空格数将比字符串数组长度少一。 现在,让我们看看这个想法是否有效: @TestvoidgivenString_whenCountSpaceBySplit_thenReturnsExpectedCount()...
