Use a Scanner object and its method nextLine to get an entir

Use a Scanner object and its method nextLine() to get an entire line of text as input and assign it to a String variable line1. Print line1 On one line, print every other character of line1 and then print a new line. Print line1 from the second character to the end and tack on the first character at the end of the output. For example, if the input is \"Java is good\", the output would be \"ava is goodJ\". Print line1 in all uppercase using a String method toUpperCase(). Using the Scanner object, get another line of text called line2. Using the String method compareTo(), print the two lines in alphabetical order.

Solution

Hi, Please find my implementation.

Please let me know in case of any issue.

import java.util.Scanner;

public class LinePrint {

  

   public static void main(String[] args) {

      

       // creating an Scanner Object

       Scanner sc = new Scanner(System.in);

      

       //1 getting line1 test

       String line1 = sc.nextLine();

      

       // 2. print line1

       System.out.println(line1);

      

       // 3 print each character of line1 on separate line

       for(int i=0; i<line1.length(); i = i+2)

           System.out.print(line1.charAt(i));

       System.out.println();

      

       // 4 print from second character and print first character at last

       for(int i=1; i<line1.length(); i++)

           System.out.print(line1.charAt(i));

       System.out.println(line1.charAt(0)); // printing first character at last

      

       // 5 print all character of line1 in uppercase

       System.out.println(line1.toUpperCase());

      

       // 6 getting another line

       String line2 = sc.nextLine();

      

       if(line1.compareTo(line2) > 0){// line1 > line2

           System.out.println(line2);

           System.out.println(line1);

       }

       else{ // line1 <= line2

           System.out.println(line1);

           System.out.println(line2);

       }

   }

}
