JAVA Check for multiple strings ending with a regex pattern in a sentence

I have a sentence jafjaklf domain1-12-123.eng.abc.com amkfg,fmgsklfgm domain2-134-135.eng.abc.com. I want to replace the words ending with .eng.abc.com with "".

I used the regex pattern:

\b(.*\.eng\.abc\.com)\b

But it matches " domain1-12-123.eng.abc.com amkfg,fmgsklfgm domain2-134-135.eng.abc.com".

Could anyone help me with the pattern

It seems that the "words" you want to match may contain non-word chars. I suggest matching those parts with a \S, non-whitespace pattern:

\b\S*\.eng\.abc\.com\b

See the regex demo

Details:

  • \b - a word boundary
  • \S* - 0+ chars other than whitespace
  • \.eng\.abc\.com - a literal .eng.abc.com substring
  • \b - end of word.

Do not forget to double the backslashes in the Java string literal.

Java demo:

String s = "jafjaklf domain1-12-123.eng.abc.com amkfg,fmgsklfgm domain2-134-135.eng.abc.com";
String pat = "\\s*\\b\\S*\\.eng\\.abc\\.com\\b";
String res = s.replaceAll(pat ,"");
System.out.println(res);
// =>  jafjaklf amkfg,fmgsklfgm

if(str.matches(".*com.?$") || str.matches(".*abc.?$") || str.matches(".*eng.?$"))

You don't need to use regex, you can use String.endsWith and String.substring:

String str = "domain1-12-123.eng.abc.com amkfg,fmgsklfgm domain2-134-135.eng.abc.com";
if (str.endsWith(".eng.abc.com")) {
    str = str.substring(0, str.length() - 12);
}
System.out.println(str); // domain1-12-123.eng.abc.com amkfg,fmgsklfgm domain2-134-135
