PROGRAM 19 : ENTER A STRING TO FIND THE LONGEST WORD AND ITS LENGTH.

Example :

PROGRAM :

import java.util.Scanner;
public class wordlengthver2
{
    public static void main(String args[]){
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter a string to find longest length:");
        String str = sc.nextLine();
        str = str + " "; // SPACE ADDED TO ENSURE STOPPAGE OF COMPARING AT THE END
        int m = 0 , p;
        String max = "" , c = ""; // CREATING TEMPORARY VARIABLES
        String min = str.substring(0 , str.indexOf(' ')); // EXTRACTS THE FIRST WORD OF STRING
        int l = min.length(); // FINDS ITS LENGTH
        char ch;
        for(int i = 0 ; i<str.length() ; i++){
            ch = str.charAt(i);
            if(ch!=' ') // CHECKING WHETHER EACH CHARACTER IS A WHITE SPACE OR NOT.
                c+=ch; // IF NOT SPACE THAN A WORD IS CREATED
            else{
               p = c.length(); // LENGTH OF THE EXTRACTED WORD.
               if(p>m){ // CHECKS IF THE LENGTH IS GREATER OR NOT
               m = p;
               max = c;
              }
              if(p<l){ // CHECKS IF LENGTH IS LESS
                min = c;
                l = p;
                }
               p = 0; // RESET TO ZERO FOR ANOTHER WORD
               c = "";
            }
        }
        System.out.println();
        System.out.println("LONGEST WORD IN STRING: " + max);
        System.out.println("LENGTH OF THE LONGEST WORD: " + m);
        System.out.println();
         System.out.println("SHORTEST WORD IN STRING: " + min);
        System.out.println("LENGTH OF THE SHORTEST WORD: " + l);
    }
}
