Regex for certain words causes Spaces












2















For instance i'm trying to search this string



"this is a search LLC which can end up having spaces"



using the below regex, it's working fine but when I match and then remove it's causes a bunch of white spaces, so I want to limit the number the white space to just 1, how could I go about adding that?



(?i)(?<=|^)LLC|end|having(?=|$)



this is a search LLC which can end up having spaces



this is a search which can up spaces



public static String removeValuesByRegex(String input, Pattern pattern, String replaceWith){

    String result;



    Matcher matcher = pattern.matcher(input);



    return result = matcher.replaceAll(replaceWith).trim();

}


Then in my test class im doing



String keywords = 'LLC|end|Having';

Pattern pattern = Pattern.compile('(?i)(?<= |^)'|' + keyWords + ''|(?= |$)');



String stringResult = UtilString.removeValuesByRegex('This is a LLC and General Partnership Test ', pattern, '');

          If you want to remove duplicate spacing, I recommend you call normalizeSpace on the output:



          String result = MyClass.myMethod(input, pattern, '').normalizeSpace();


          Note from the documentation:




          normalizeSpace()

          Returns the current String with leading, trailing, and repeating white space characters removed.
