regular expression for matching a pattern in Pattern class in java

Question

I have a string m="hell,hj;nk,.txt"

I want my string as string m="hellhjnk.txt"

I am using:

 Pattern p=Pattern.compile("(\"([^\"]*)(\\.)([a-z]{1,4}[\"]))|'([^']+)(\\.)([a-z]{1,4})'");

It is working for double quotes and extension. How it will work for removing space,comma,semicolon?

You could just do:

m = m.replaceAll("[,; ]","");

The Pattern class is used for matching. You can essentially do the same thing:

     Pattern p = Pattern.compile("[;, ]");
     String m = "hell,hj;nk,.txt";
     Matcher matcher = p.matcher(m);
     System.out.println(matcher.replaceAll(""));
