regex problem!!!

[James Basller]

Hi All,

I am very new to regex. I know that it's used for matching patterns. But I want to know that is there anything in regex which can substring my string. I don't want to use String's substring function.

For example,

if I have a string 1234567890123456. In this 16 length char string I just want only last 6 chars.

Can I do this with regex? If yes can anyone provide me solution???

Thanks!!!

I don't want to use String's substring function.

Why not? It would be the natural (and easiest) solution for this.

Although I agree with Ulf, I'll help you out nonetheless.

Do you know how to match one digit?
Do you know how to match six digits?
Do you know how to match the end of input?

Combine those, and there is your regular expression: 6 digits directly followed by the end of input.

String targetString = "473867689677473867483" 		
Matcher matcher = pattern.matcher(targetString); 
if (matcher.find()) { 
    System.out.println("Found a match: " + matcher.group()); 
}
