例子 (Example)
以下示例显示了java.util.regex.Matcher.reset()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);
matcher.region(10, 15);
System.out.println("Before reset, regionStart(): " + matcher.regionStart());
System.out.println("Before reset, regionEnd(): " + matcher.regionEnd());
matcher.reset();
System.out.println("After reset, regionStart(): " + matcher.regionStart());
System.out.println("After reset, regionEnd(): " + matcher.regionEnd());
}
}
让我们编译并运行上面的程序,这将产生以下结果 -
Before reset, regionStart(): 10
Before reset, regionEnd(): 15
After reset, regionStart(): 0
After reset, regionEnd(): 18
