boolean find() - 声明
以下是 java.time.Matcher.find()方法的声明。
public boolean find()
boolean find() - 返回值
当且仅当输入序列的子序列匹配此匹配器的模式时，才返回true。
boolean find() - 示例
下面的示例显示java.time.Matcher.find()方法的用法。
package com.learnfk;
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);

}
}
让无涯教程编译并运行以上程序，这将产生以下输出-
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
