boolean matches() - 示例
下面的示例显示java.time.Matcher.matches()方法的用法。
package com.learnfk;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MatcherDemo {
private static final String REGEX = "foo";
private static final String INPUT = "fooooooooooooooooo";
private static Pattern pattern;
private static Matcher matcher;
public static void main( String args[] ) {
pattern = Pattern.compile(REGEX);
matcher = pattern.matcher(INPUT);

</span><span class="typ">System</span><span class="pun">.</span><span class="kwd">out</span><span class="pun">.</span><span class="pln">println</span><span class="pun">(</span><span class="str">"matches(): "</span><span class="pun">+</span><span class="pln">matcher</span><span class="pun">.</span><span class="pln">matches</span><span class="pun">());</span><span class="pln">
}
}
让无涯教程编译并运行以上程序，这将产生以下输出-
Current REGEX is: foo Current INPUT is: fooooooooooooooooo lookingAt(): true matches(): false
