How to search word in String text, this word end "." or "," in java

Question

someone can help me with code? How to search word in String text, this word end "." or "," in java

I don't want search like this to find it

String word = "test.";

String wordSerch = "I trying to tasting the Artestem test.";

String word1 = "test,"; // here with ","

String word2 = "test."; // here with "."

String word3 = "test";  //here without 

//after i make string array and etc...

if((wordSearch.equalsIgnoreCase(word1))||
   (wordSearch.equalsIgnoreCase(word2))||
   (wordSearh.equalsIgnoreCase(word3))) {
}

if (wordSearch.contains(gramer)) 
//it's not working because the word Artestem  will contain test too, and I don't need it

Have you done some research? Based on your needs, `contains`, `startWith`, ... from String or a Regex will do it, there is enough existing source I believe to find what you need — AxelH, Feb 15 '17 at 13:51
Your question doesn't make much sense. You may find `String.endsWith()` useful though. — Steve Smith, Feb 15 '17 at 13:51
What about using regex (as pointed by AxelH)? http://stackoverflow.com/questions/9464261/how-to-find-the-exact-word-using-a-regex-in-java — RubioRic, Feb 15 '17 at 13:52
Explain what you want because this is not clear. Adding some example is always a good idea. But I am pretty sure this is a simple search that could be answer by Google — AxelH, Feb 15 '17 at 13:55
thank you The complex question :) My second language is English so sorry for my words non-clear I am researching within the text through the words stored in a Array, so looking for a way to shorten the code — Ahmad Al ALloush, Feb 15 '17 at 18:57

You can use the matches(Regex) function with a String

String word = "test.";
boolean check = false;
if (word.matches("\w*[\.,\,]") {
    check = true;
}

You can use regex for this

Matcher matcher = Pattern.compile("\\btest\\b").matcher(wordSearch);
if (matcher.find()) {
}

\\b\\b will match only a word. So "Artestem" will not match in this case. matcher.find() will return true if there is a word test in your sentence and false otherwise.

String stringToSearch = "I trying to tasting the Artestem test.   test,";

Pattern p1 = Pattern.compile("test[.,]");
Matcher m = p1.matcher(stringToSearch);

while (m.find())
{
    System.out.println(m.group());   
}

What is a word? E.g.:

Is '5' a word?
Is '漢語' a word, or two words?
Is 'New York' a word, or two words?
Is 'Kraftfahrzeughaftpflichtversicherung' (meaning "automobile liability insurance") a word, or 3 words?

For some languages you can use Pattern.compile("[^\\p{Alnum}\u0301-]+") for split words. Use Pattern#split for this.

I think, you can find word by this pattern:

String notWord = "[^\\p{Alnum}\u0301-]{0,}";
Pattern.compile(notWord  + "test" + notWord)`

You can transform your String in an Array divided by words(with "split"), and search on that array , checking the last character of the words(charAt) with the character that you want to find.

String stringtoSearch = "This is a test.";
String whatIwantToFind = ",";

String[] words =  stringtoSearch.split("\\s+");
for (String word : words) {
    if (whatIwantToFind.equalsignorecas(word.charAt(word.length()-1);)) {
        System.out.println("FIND");

    }
}
