Preg_match PHP to java translation

java, php, preg-match

Solution

To implement a function as you did in your code:

final String pattern = "[0-9A-F\\-]{44}";
public static boolean pregMatch(String pattern, String content) {
    return content.matches(pattern);
}

And then you can call it as:

if (pregMatch(pattern, line)) {
    //DO ACTION
}

You don't need the parenthesis in your `pattern` because that just creates a match group, which you are not using. If you need access to back references, you would need the parenthesis an a more advanced regex code using `Pattern` and `Matcher` classes.

Problem

I am having some trouble converting a php pregmatch to java. I thought I had it all correct but it doesn't seem to be working. Here is the code: Original PHP: ``` /* Pattern for 44 Character UUID */ $pattern = "([0-9A-F\-]{44})"; if (preg_match($pattern,$content)){ /*DO ACTION*/ } ``` My Java code: ``` final String pattern = "([0-9A-F\\-]{44})"; public static boolean pregMatch(String pattern, String content) { Pattern p = Pattern.compile(pattern); Matcher m = p.matcher(content); boolean b = m.matches(); return b; } if (pregMatch(pattern, line)) { //DO ACTION } ``` So my test input is: DBA40365-7346-4DB4-A2CF-52ECA8C64091-0 Using a series of System.outs I get that b = false.
