Count number of words in a String
public static void main (String[] args) {

String str1 = "Today is Holdiay Day";
String[] wordArray = str1.trim().split("\\s+");
int wordCount = wordArray.length;
System.out.println("Word count is = " + wordCount);
}check how many of a word is in a string
function countOccurences(str,word)

// search for pattern in a
int count = 0;

count++;
}

}how to count number of words in a string
String name = "Carmen is a fantastic play"; //arbitrary sentence
int numWords = (name.split("\\s+")).length; //split string based on whitespace
//split returns array - find legth of array
System.out.println(numWords);how to count words in string
