Take two String inputs of the same length and merge these by taking one character from each String (starting with the first entered) and alternating. If the Strings are not the same length, the program should print "error".

Answer 1

import java.util.Scanner;

public class JavaApplication68 {

   

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       System.out.println("Enter Strings:");

       String txt1 = scan.nextLine();

       String txt2 = scan.nextLine();

       String newTxt = "";

       if (txt1.length() != txt2.length()){

           System.out.println("error");

       }

       else{

           for (int i = 0; i < txt1.length(); i++){

               char c = txt1.charAt(i);

               char d = txt2.charAt(i);

               newTxt += c+""+d;

           }

           System.out.println(newTxt);

       }

       

   }

   

}

I hope this helps! BTW, I've completed a bunch of java problems similar to the ones you're posting now. If you want to check them out instead of spending your points, that might be something to look into.
