public static void main(String[] args) {
String[] strs = {"mn","mon","mea","moon","meeeeen","cmon","mona"};
Pattern pattern = Pattern.compile("^m[a-zA-Z]*n$");
for(String str : strs) {
Matcher m = pattern.matcher(str);
System.out.println(m.find());

上面的正则不能批评汉字还有一些标点等，下面是非空格的字符都可以。
public static void main(String[] args) {
String[] strs = {"mn","mon","mea","moon","meeeeen","cmon","mona","m n","m好好好n"};
Pattern pattern = Pattern.compile("^m[^ ]*n$");
for(String str : strs) {
Matcher m = pattern.matcher(str);
System.out.println(m.find());
}
}

public static void main(String[] args) {
String input = "ihaomdkinkkmkkkiihiinkkoh" ;
String regex = "(m[^n]*n)" ;
Pattern pattern = Pattern.compile(regex);
Matcher m = pattern.matcher(input) ;
while(m.find()){
System.out.println(m.group(1));
}
}
输出结果是:
mdkin
mkkkiihiin
