边界匹配器 [\Z] 匹配输入的末尾,但匹配最终终止符(如果有)。
Z - 示例
以下示例显示了边界匹配器的用法。
package com.learnfk; import java.util.regex.Matcher; import java.util.regex.Pattern; public class BoundaryMatcherDemo { private static final String REGEX = "\\Z"; private static final String INPUT = "Welcome to LearnFk.COM"; public static void main(String[] args) { //创建一个模式 Pattern pattern = Pattern.compile(REGEX); //获取匹配对象 Matcher matcher = pattern.matcher(INPUT); while(matcher.find()) { //打印匹配的起始索引。 System.out.println("Match String start(): "+matcher.start()); } } }
让无涯教程编译并运行以上程序,这将产生以下输出-
Match String start(): 29
