java.util.regex.Matcher.reset() 方法
描述
java.util.regex.Matcher.reset(CharSequence input) 方法使用新的输入序列重置此匹配器。
声明
以下是 java.util.regex.Matcher.reset(CharSequence input) 方法的声明。
public Matcher reset(CharSequence input)
参数
input − 新的输入字符序列。
返回值
此匹配器。
示例
下面的例子展示了 java.util.regex.Matcher.reset(CharSequence input) 方法的用法。
package com.tutorialspoint;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MatcherDemo {
private static String REGEX = "(a*b)(foo)";
private static String INPUT = "aabfooaabfooabfoob";
private static String INPUT1 = "fooabfoob";
private static String REPLACE = "-";
public static void main(String[] args) {
Pattern pattern = Pattern.compile(REGEX);
// get a matcher object
Matcher matcher = pattern.matcher(INPUT);
while(matcher.find()) {
//Prints the offset after the last character matched.
System.out.println("First Capturing Group, (a*b) Match String end(): "+matcher.end());
}
matcher.reset(INPUT1);
System.out.println("RESET");
while(matcher.find()) {
//Prints the offset after the last character matched.
System.out.println("First Capturing Group, (a*b) Match String end(): "+matcher.end());
}
}
}
让我们编译并运行上面的程序，这将产生以下结果 −
First Capturing Group, (a*b) Match String end(): 6 First Capturing Group, (a*b) Match String end(): 12 First Capturing Group, (a*b) Match String end(): 17 RESET First Capturing Group, (a*b) Match String end(): 8
