To find the number of words in the given String in java is easy . Here we are using arrays and string class to achieve our goal .
For example :
Original String : "I love music"
If we pass the above string in the getWordcount method then it will return
Output : 3
Here we are passing String to the getWordcount() function which return the int value that is the number of words in the string .
Please find the code below :

Please find the code below :
public class StringDemo { static int i,c=0,res; static int getWordcount(String s) { char ch[]= new char[s.length()]; //in string especially we have to mention the () after length for(i=0;i<s.length();i++) { ch[i]= s.charAt(i); if( ((i>0)&&(ch[i]!=' ')&&(ch[i-1]==' ')) || ((ch[0]!=' ')&&(i==0)) ) c++; } return c; } public static void main (String args[]) { res=StringDemo.getWordcount("I love music"); //string is always passed in double quotes System.out.println("The number of words in the String are : "+res); } }
