Java provides the String.split() method to split a string into an array based on the given regular expression. Here is an example: String fruits = "Orange:Mango:Apple:Banana"; // split string into an array Strin
public String[] split(String regex)这个方法根据给定的正则表达式来拆分字符串，并返回一个字符串数组。例如，可以使用空格作为分隔符来分割字符串：String s = "The rain in Spain falls mainly in the plain.";String[] ss = s.split(" ");这段代码将在每个空格字符处分割字符串，并将结果存...
StringblogName="how,to,do,in,java";String[]tokenArray=blogName.split(",");//["how", "to", "do", "in", "java"] We need to modify the regex expression for any additional requirements. Such for ignoring the whitespaces around commas, we can use the pattern “\\s,\\s”. String[...
public class SplitDemo2 { public static String[] ss = new String[20]; public SplitDemo2() { // String s = "The rain in $$$ Spain falls mainly in the plain."; String s = "XXXXX$$$YYYYY"; // 在每个空格字符处进行分解。 // ss = s.split(" ",4); // 在每个空格字符处进行分...
String.split方法 使用String.split方法时要注意的问题在使用String.split方法分隔字符串时,分隔符如果用到一些特殊字符,可能会得不到我们预期的结果。我们看jdk doc中说明public String[] split(String regex)Splits this string around matches of the given regular expression.参数regex是一个 regular-expression的匹...
Java中split方法的细节问题。 先看一段代码: + View Code 你会觉得长度应该不是1,那是为什么呢? 看一下jdk中关于方法的说明。 split publicString[]split(Stringregex) Splits this string around matches of the givenregular expression. This method works as if by invoking the two-argumentsplitmethod with...
百度之,原来java中还有 split(String regex, int limit)这中用法,String[]java.lang.String.split(Stringregex, int limit),其中regex为分割正则表达式,limit为分割次数限制,官方文档这样解释: 1. Thelimitparameter controls the number of times the pattern is applied and therefore affects the length of the ...
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一下。

public String[]split(String regex)Splits this string around matches of the given regular expression.参数regex是一个 regular-expression的匹配模式而不是一个简单的String，他对一些特殊的字符可能会出现你预想不到的结果，比如测试下面的代码：用竖线 | 分隔字符串，你将得不到预期的结果 String[] aa = "...
