如何计算每个单词的字母

Question

I was wondering how I would write a method to count the number of words and number of each word letters for example if input is "The Blue Sky" in return i take something that show me there was 3 words 3 letter 4 letter 3 letter

i'v found this code already

public static int countWords(String s){

    int wordCount = 0;

    boolean word = false;
    int endOfLine = s.length() - 1;

    for (int i = 0; i < s.length(); i++) {
        // if the char is a letter, word = true.
        if (Character.isLetter(s.charAt(i)) && i != endOfLine) {
            word = true;
            // if char isn't a letter and there have been letters before,
            // counter goes up.
        } else if (!Character.isLetter(s.charAt(i)) && word) {
            wordCount++;
            word = false;
            // last word of String; if it doesn't end with a non letter, it
            // wouldn't count without this.
        } else if (Character.isLetter(s.charAt(i)) && i == endOfLine) {
            wordCount++;
        }
    }
    return wordCount;
}

I really appreciate any help I can get! Thanks!

Answer 1

Step 1 - Find the number of words in the sentence using the space separator.

 String CurrentString = "How Are You";
    String[] separated = CurrentString.split(" ");
    String sResultString="";
    int iWordCount = separated.length;
    sResultString = iWordCount +" words";

Step 2 - Find letter count in each word.

    for(int i=0;i<separated.length;i++)
    {
    String s = separated[i];
    sResultString = sResultString + s.length + " letters ";
    }

// Print sResultString 

Answer 2

Take a look at http://www.tutorialspoint.com/java/java_string_split.htm . You should be able to use the Java String.split() function to break up the string by spaces " ". That should give you an array that contains each word. Then it is simply finding the length of each word.

to count words this might help

  public static int countWords(String str)
        {
            int count = 1;
            for (int i=0;i<=str.length()-1;i++)
            {
                if (str.charAt(i) == ' ' && str.charAt(i+1)!=' ')
                {
                    count++;
                }
            }
            return count;
        }
        public static void main(String[] args)
        {
            Scanner in = new Scanner(System.in);
            System.out.print("Enter a sentence: ");
            String sentence = in.nextline();
            System.out.print("Your sentence has " + countWords(sentence) + " words.");
        }

Answer 4

Here is my code-

   public void countWordsLetters(String s){
        String str[]=s.split(" ");
        System.out.println("No. of words in string::"+str.length);
        for (int i=0;i<str.length;i++){
            System.out.println("No of letters in "+i+" word "+str[i].length());
        }
    }

Answer 5

Buddy, most of the above answers are correct but nobody considered the whitespace while counting the characters in String. Hope you can also include that.

          for(int j=0;j<name.length();j++){ //here is name is my string

          if(Character.isWhitespace(name.charAt(j))){

            }else{
                count+=1;
            }

      }
      System.out.println("The word count is "+count);

Answer 6

this is my answer thanks to Sahil Nagpal for the inspiration:

package exercise;

import java.util.Scanner;

public class method_letter {

public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    System.out.println("enter any string");
    String s=in.nextLine();
    System.out.println("the letter count :"+lettercount(s));

}
public static int lettercount (String s) {
    int count=0;
    for (int i=0; i<s.length(); i++) {
        if(Character.isWhitespace(s.charAt(i))){

        }else {
            count+=1;
        }
    }
    return count;
}

}
