Question

JAVA CODE FOR BEGINNERS!!

Write a program that reads three strings from the keyboard. Although the strings are in no particular order, display the string that would be second if they were arranged lexicographically.

Answer 1

import java.util.Scanner;

public class Print_Second
{
public static void main(String[] args)
{
   int i,j;
   Scanner input = new Scanner(System.in); //Reading input from keyboard
   String[] strings = new String[3]; // Initialize the no. of strings needed

   for (i = 0; i < strings.length; i++)
   {
   strings[i] = input.nextLine(); // Loop for taking three strings from keyboard
   }

   for(i = 0; i < 2; ++i)           // Loop for comparing strings and arranging them in lexicographically
   {
   for (j = i + 1; j < 3; ++j)
       {
   if (strings[i].compareTo(strings[j]) > 0) //compareTo function compares two strings
           {
               String temp = strings[i];   // Swaping the strings and keeping them in lexicographically order
   strings[i] = strings[j];
        strings[j] = temp;
   }
   }
}

  
   System.out.println("In lexicographical order Second String is :");
   System.out.println(strings[1]);                   // string[1] is the second string as string[] starts from 0 index

}

}
