The following Java program splits a string by space using the delimiter"\\s". To split by all white space characters (spaces, tabs, etc.), use the delimiter “\\s+“. Split a string by space Stringstr="how to do injava";String[]strArray=str.split("\\s");//[how, to, to, i...
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 ...
publicstaticList<String> getListByDelimiter(String str , String delimiter) { intindex; String tempString; List<String> resList =newLinkedList<>(); while((index = str.indexOf(delimiter)) >= 0) { tempString = str.substring(0, index); if(tempString!=null&& !tempString.trim().equals("")...
publicclassStringSplitter{// 根据最后一个分隔符分割字符串publicstaticString[]splitByLastDelimiter(Stringstr,Stringdelimiter){// 找到最后一个分隔符的位置intlastIndex=str.lastIndexOf(delimiter);// 如果没有找到分隔符,返回原字符串和空字符串if(lastIndex==-1){returnnewString[]{str,""};}// 使用subst...
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。
publicStringsplitStringByHex(StringhexString,Stringdelimiter){returnhexString.replaceAll("..(?!$)","$0"+delimiter);}// 代码解释:此方法使用16进制字符作为分隔符,对16进制字符串进行分割,并返回结果 1. 2. 3. 4. 步骤3:将分割后的16进制字符串转换为原始字符串 ...
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: StringTokenizer st = new StringTokenizer(str, delimiter); while (st.hasMoreTokens()) { String token = st.nextToken(); ...
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) { ...
The following Java program usingStringUtilssplits a string by delimiter whitespace. StringUtils example String[]tokens=StringUtils.split("how to do in java");Assertions.assertArrayEquals(newString[]{"how","to","do","in","java"},tokens);...
[out] = strsplitNew(str, delimiter)% str:以分隔符连接的多个字符串% delimiter:分隔符元胞数组，...
