Answer 1

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Mymatch {
private static final String REGEX = "abc";
private static final String INPUT = "abcdaabcabbbcabccabcaabcabba";

public static void main(String[] args) {
Pattern p = Pattern.compile(REGEX);
Matcher m = p.matcher(INPUT);
int i = 0;
System.out.println(m.find());
while (m.find()) {
i++;
System.out.print("Match" + i);
System.out.print(":" + m.start()); //这个是返回上一次匹配的，第一次运行到的时候会出异常
System.out.println("-" + m.end()); //上一次的，第一次运行会有异常
}
}
}
