Java如何使用正则表达式拆分字符串？
本示例使用该java.util.regex.Pattern.split()方法分割由逗号或空格分隔的输入字符串。
package org.nhooo.example.regex;
import java.util.regex.Pattern;
public class RegexSplitExample {
public static void main(String[] args) {
//查找逗号，空格（空格，制表符，换行，
//回车，换页）。
String pattern = "[,\\s]+";
String colours = "Red,White, Blue Green Yellow, Orange";
Pattern splitter = Pattern.compile(pattern);
String[] result = splitter.split(colours);
for (String colour : result) {
System.out.format("Colour = \"%s\"%n", colour);
}
}
}我们的代码片段的结果是：
Colour = "Red" Colour = "White" Colour = "Blue" Colour = "Green" Colour = "Yellow" Colour = "Orange"
