How to split symbols in a string (java)

Question

I have a task to count how many words are in a string. So I created a string[] variable_name = string.split(" ") ;
And then used a for loop to count how many words are.
And I was thinking, what if the user won't put white space at the end of sentence or after using comma, brackets etc... What should I do in order make my program to count the number of words in this case?

Answer 1

still there is something between words or something that is not words, isn't it?

Answer 2

zemiak I will write down an example
I learn Java. He learns python.
Output : 6 words
I learn Java.He learns python.
Output 5 words
As you can see, my code reads Java.He as one word because there is no space

Answer 3

I was thinking of making one more loop in order to take each word and to split it by using regex( "[!?,. :+]"), but I just make my code more complicated. So I wonder if there is a easier solution

Answer 4

Your task should have explained clearly for what you can count it as word & how it is separated by if there is nothing specifically mentioned then just simply go with white space that would be fine i think Zotta

String[] aStr = str.split("\\W+");
System.out.println( aStr.length ); //12

// if word is a-zA-Z_0-9
