Answer to Question #294112 in Java | JSP | JSF for Helen

Question

Write a program to take a String as input then display the words in one column, number of characters in each word in second column and the first letter of each word in third column with appropriate heading.

For example:

Enter a String

Hello world

Words Length First Letter

Hello 5 H

world 5 w

for(i=0;i<s.lastIndexOf(' ');i++) {

      c = s.charAt(i);

      if(c ==' ')

        s1=s1+s.charAt(i+1)+" ";

    } //Use this code for first letter

for(i=0;i<s.length();i++) {

      c = s.charAt(i);

      if (c != ' ')

        n = n+c;

      else {

        System.out.println(n+...);

       } //Use this code for display words and its number of characters

Answer 1

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.println("Enter a String");
        String s = in.nextLine();
        String s1 = s.charAt(0) + "";
        for (int i = 0; i <= s.lastIndexOf(' '); i++) {
            char c = s.charAt(i);
            if (c == ' ') {
                s1 = s1 + s.charAt(i + 1);
            }
        } //Use this code for first letter

        String n = "";
        System.out.println("Words Length First Letter");
        for (int i = 0, j = 0; i < s.length(); i++) {
            char c = s.charAt(i);
            if (c != ' ') {
                n = n + c;
            }
            if (c == ' ' || i == s.length() - 1) {
                System.out.println(n + " " + n.length() + " " + s1.charAt(j++));
                n = "";
            }

        } //Use this code for display words and its number of characters
    }
}
