Programmers often use differentregular expressionsto define a search pattern for strings. They’re also a very popular solution when it comes to splitting a string. So, let’s see how we can use a regular expression to split a string by multiple delimiters in Java. First, we don’t need ...
String str = "Hello world, this is a test."; String[] result = str.split(" ");执行上述代...
Java program to split a string by delimitercomma. Split a string with a comma Stringstr="A,B,C,D";String[]strArray=str.split(",");//[A,B,C,D] 2.4. Split by Multiple Delimiters By using regular expressions and character classes in the regular expression, we can split a string based...
2.3 使用StringTokenizer类进行分割 除了使用内置的split()方法外,Java中还提供了StringTokenizer类来实现字符串的分割。该类的使用方法如下: 其中,str是要进行分割的字符串,delimiter是分割符,st是StringTokenizer类的实例,hasMoreTokens()方法用于判断是否还有剩余的字符串,nextToken()方法用于获取下一个分割后的字符串。
Using thesplitMethod in Java Thesplitmethod in Java is used to split a string into an array of substrings based on a specified delimiter. By default, the delimiter is a regular expression, which allows for flexibility in defining the splitting criteria. ...
I have a string,"004-034556", that I want to split into two strings: 我有一个字符串,“004-034556”,我想把它分成两个字符串: string1=004 string2=034556 1. 2. That means the first string will contain the characters before'-', and the second string will contain the characters after'-...
max(Optional) – the maximum number of elements to include in the array. A zero or negative value implies no limit. The following Java program usingStringUtilssplits a string by delimiter whitespace. StringUtils example String[]tokens=StringUtils.split("how to do in java");Assertions.assertArray...
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) { ...
publicString[] split(String regex,intlimit) 如果limit是负数,那么它会尽可能匹配到所有的这个数组的个数,如果是0那么尽可能匹配出现的元素,但是空字符串将会被就丢弃,但我们不希望它丢弃,因为丢弃就意味着有业务字段缺失,所以来看下最终的写法: Java代码 ...
