m new to programming i want to find no. of words in any string so can anybody have any logic if yas then tell me,,,,

[rakesh0]

please give me some code for that purpose,,,,,,

[bcranger]

Number of words...maybe try using the split() method and split according to whitespaces?

And count the length of the array returned by that method:

String[] words = sentence.split(" ");
//words.length is your # of words

[rakesh0]

i still not getting the output can you send me the code,,,,??? piz m new to programming

We will not write code for you, feel free to provide some code you have done to show us that you have put effort in.

Which is exactly why we shouldn't send you the code. If you just always have code handed to you then you will not learn. Post what you've done. You said you're not getting the desired output so you must have done something.

Let's see it!

Title renamed to be more descriptive. Please respect rule #4 of this forum. "Java" is not a helpful title in a forum dedicated to Java Programming.

Also, I want to reiterate rule #1. We will be happy to help you debug code you wrote, but we will not give you the code.

Here's a hint. Do what bcranger said, and use a for loop to iterate through the "word" array, use equals() method to find which word is equal to the word you want to find, and increase a "count" variable when the word is equal. I hope this is clear enough to give you a headstart. Well, actually it's clear enough to let you write the whole app. XD

I think he just wants the number of words. If you provide a string to that snippet bcranger gave you, it works out the number of words for you. All you need then is a System.out.println(???????) to display them.

Leave that for him/her to do atleast

[rakesh0]

actually what m trying to do is..m trying to count the no. of words usig that code but unable to do,,,,,help me

class words
{
     public static void main (String args[])
        {
                 String name="welcome to java";
                 int l=0;
                 int i;
                 int j;
                 for(i=0;i<name.length;i++)
                 {
                      for(j=0;j<=name[i].length()-1;i++)
                                   {
                                     if(name[i].charAt(i)==' ')
                                    {
                                        l++;
                                    }
     }
}
System.out.println(+l);
}}

Well why not try what bcranger said? You don't need any loops for this.

rakesh0, please use code tags, like so: . Also, please properly format your code so we can read it easier. Why don't you just use bcranger's solution?

macosxnerd101, could you merge this thread?

[macosxnerd101]

They are different topics, as that one is trying to find the number of occurrences of a character in a String. I'm going to keep the topics as they are for now.
