boolean find()

描述 (Description)

java.time.Matcher.find()方法尝试查找与模式匹配的输入序列的下一个子序列。

声明 (Declaration)

以下是java.time.Matcher.find()方法的声明。

public boolean find()

返回值 (Return Value)

当且仅当输入序列的子序列与此匹配器的模式匹配时才返回true。

例子 (Example)

以下示例显示了java.time.Matcher.find（）方法的用法。

package cn.xnip;
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 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());    
         System.out.println("Second Capturing Group, (foo) Match String end(): "+matcher.end(1));  
      }
   }
}

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
Second Capturing Group, (foo) Match String end(): 3
First Capturing Group, (a*b) Match String end(): 12
Second Capturing Group, (foo) Match String end(): 9
First Capturing Group, (a*b) Match String end(): 17
Second Capturing Group, (foo) Match String end(): 14
