描述 (Description)
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 (Declaration)
以下是java.util.regex.Matcher.reset(CharSequence input)方法的声明。
public Matcher reset(CharSequence input)
参数 (Parameters)
input - 新的输入字符序列。
返回值 (Return Value)
这个匹配器。
例子 (Example)
以下示例显示了java.util.regex.Matcher.reset（CharSequence input）方法的用法。
package com.iowiki;
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
