Regular Expression to match a string that does not contain specific string in Java

Question

I need a regular expression that matches a substring in string /*exa*/mple*/ ,

the matched string must be /*exa*/ not /*exa*/mple*/.

It also must not contain "*/" in it.

I have tried these regex:

"/\\*[.*&&[^*/]]\\*/" ,
"/\\*.*&&(?!^*/$)\\*/"

but im not able to get the exact solution.

Try this [How to find the exact word using a regex in Java?](http://stackoverflow.com/questions/9464261/how-to-find-the-exact-word-using-a-regex-in-java) — Perdomoff, Nov 12 '15 at 17:20
Simplest would be to use two regex's, match rexexp1 && ~ regexp2 — Sanjay Manohar, Nov 12 '15 at 17:21

you can try this:

/\*[^\*\/\*]+\*/   --> anything that is in between (including) "/*" and "*/"

Here is a sample:

    Pattern p = Pattern.compile("/\\*[^\\*\\/\\*]+\\*/");
    Matcher m = p.matcher("/*exa*/mple*/");
    while (m.find()){
        System.out.println(m.group());
    }

OUTPUT:

/*exa*/

I understand you want to pick out comments from a text.

Pattern p = Pattern.compile("/\\*.*?\\*/");
Matcher m = p.matcher("/*ex*a*/mple*/and/*more*/ther*/");
while (m.find()){
    System.out.println(m.group());
}
