Question

I need a regular expression which will match a string only if it doesn’t followed by a forward slash (/) character and I want to match whole string.

For example below string should match

/Raj/details/002-542545-1145457

but not this one

/Raj/details/002-542545-1145457/show

I tried to use Negative Lookahead to achieve this as specified by this answer.

My code is like this.

pattern = Pattern.compile("/.*/details/(?!.*/)");
matcher = pattern.matcher(text);
if(matcher.matches()) {
  System.out.println("success");
} else {
System.out.println("failure");
}

It is giving failure. But if I use matcher.find() then it is giving success.

Please help me understanding why it is not matching and a reg-exp to achieve this?

Answer 1

This

^/[^/]+/details/[^/]+$

will match

/Raj/details/002-542545-1145457

but not

/Raj/details/002-542545-1145457/show
