Java中Matcher toMatchResult()方法的示例
java.util.regex.Matcher类表示执行各种匹配操作的引擎。该类没有构造函数，可以使用matches()类java.util.regex.Pattern的方法创建/获取该类的对象。
此（匹配器）的toMatchResult()方法返回当前匹配器的匹配状态。
例子1
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class ToMatchResultExample {
public static void main(String[] args) {
String str = "<p>This <b>is</b> an <b>example</b>.</p>";
//正则表达式以匹配粗体标签的内容
String regex = "<b>(\\S+)</b>";
//创建一个模式对象
Pattern pattern = Pattern.compile(regex);
//匹配字符串中的已编译模式
System.out.println("State of the matcher: ");
Matcher matcher = pattern.matcher(str);
while (matcher.find()) {
System.out.println(matcher.toMatchResult());
String result = matcher.group(1);
}
matcher = matcher.reset("<p>this is another <b>line</b>.</p>");
matcher.find();
System.out.println("");
System.out.println("State of the matcher after resetting it: \n"+matcher.toMatchResult());
}
}输出结果
State of the matcher: java.util.regex.Matcher[pattern=<b>(\S+)</b> region=0,40 lastmatch=<b>is</b>] java.util.regex.Matcher[pattern=<b>(\S+)</b> region=0,40 lastmatch=<b>example</b>] State of the matcher after resetting it: java.util.regex.Matcher[pattern=<b>(\S+)</b> region=0,35 lastmatch=<b>line</b>]
例子2
import java.util.Scanner;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class ToMatchResultExample {
public static void main(String[] args) {
String regex = "[#]";
System.out.println("Enter a string: ");
Scanner sc = new Scanner(System.in);
String input = sc.nextLine();
//创建一个模式对象
Pattern pattern = Pattern.compile(regex);
//创建一个Matcher对象
Matcher matcher = pattern.matcher(input);
System.out.println("Match state: ");
//找到比赛
while(matcher.find()) {
System.out.println(matcher.toMatchResult());
}
}
}输出结果
Enter a string: #This #is #a #sample #text Match state: java.util.regex.Matcher[pattern=[#] region=0,26 lastmatch=#] java.util.regex.Matcher[pattern=[#] region=0,26 lastmatch=#] java.util.regex.Matcher[pattern=[#] region=0,26 lastmatch=#] java.util.regex.Matcher[pattern=[#] region=0,26 lastmatch=#] java.util.regex.Matcher[pattern=[#] region=0,26 lastmatch=#]
