Knowing how many words are in each string sentence?

[vahid mirjamal]

I've been working all day on trying to get a paragraph string, and finding out how many sentences it has, how many words it has in each sentence, and which words are small words (below 4 letters.)

I'm totally not getting it.

   import javax.swing.JOptionPane;
 import java.util.StringTokenizer;
 import java.util.*;
public class EssayCounters {
	
	int sentencecount = 0; // Starts the Sentence count from 0 
	int WordCount = 0;
  	int shortWordLength = 4;   //If it's below 4 letters it's a short word.
    int longWordLength = 4; // Will be used to determine long words.
  	int wordwithinsentence = 0;// Counts the words within the sentences.
    
    public static void main(String[] args) {
    	
    	String essayInput  = 
  			JOptionPane.showInputDialog("Type in your Essay Below:");
   
String[] tokens = essayInput.split("[.?!]");
int numTokens = tokens.length;
String[] words = essayInput.split(" ");
int numwords = words.length;


  System.out.println("Number of tokens: " + numTokens); 
  System.out.println("Number of words: " + numwords); 
  			 
   
          System.exit(0);
    }
}  

Any hints? I'm totally stuck at a dead end and i've been sitting here trying to figure this out for around.. 5 hours so far non stop with searching and so far. I believe it needs loops to determine most of these but i just don't know where to start.

What else have you tried during those 5 hours? Maybe some of the ideas that you had, or code that you attempted, and failed, where actually good ideas, and we can give you a hint in the right direction.

After 5 hours, you must have tons of questions to ask.

Hehe your so right, I'm starting to go back and see my old code and it's not all bad. Like I got here so far:

for (int i=0;i<numTokens;i++)
{
	String[] wordspersentence = tokens[i].split("[ ]+");
	int numwordspersentence = wordspersentence.length;
	System.out.println("Number of Words per Sentence: " + numwordspersentence);
	
}

But for for some reason it counts the extra spaces as an extra word, how can i get it to stop counting the extra space? If i figure that out I should be closer to figuring this out. I got it to exclude double spaces, etc from my first regex:

String[] words = essayInput.split("[ ]+");

But it doesn't seem to be working in the counting words one..

The extra space is probably in the beginning of the sentence -- as people generally put a space after the period from the previous sentence. You may want to consider trimming the sentence before splitting it.

Another option is to loop through the word list (after the sentence is split) and check to make sure that every word has at least 1 character. If it is splitting an extra word due to an extra space, the extra word should be a zero-length string.

 	String userEssay  = 
  			JOptionPane.showInputDialog("Type in your Essay Below:");
 String essayInput = userEssay.trim(); // Trim the user input. 
String[] tokens = essayInput.split("[.?!]+");
int numTokens = tokens.length;
String[] words = essayInput.split("[ ]+");
int numwords = words.length;

 System.out.println("Number of tokens: " + numTokens); 
 System.out.println("Number of words: " + numwords); 
  	
for (int i=0;i<numTokens;i++)
{
	String[] wordspersentence = tokens[i].split("[ ]");
	int numwordspersentence = wordspersentence.length;
	System.out.println("Number of Words per Sentence: " + numwordspersentence);
	

}   

Like that?

Because it's not exactly working :|

Like that?

Actually, no.... I suggested that you trim the sentence. Not the paragraph. (And it was only speculation, as you never showed us the actual symtoms).

I also suggested that you count the words -- by checking if the length is greater than zero -- which you didn't even attempt.

Because it's not exactly working :|

Statements like "it's not exactly working" is completely useless here. You need to describe what you did. what you expected, what you got, and.... You need to attempt to debug the code to try to isolate where the problem is. Or at least speculate.
