Question

Today you are to write a Java program that will prompt for and read 2 words of equal length entered by the user, and create a new word which contains the last letter of the 1st word, the last letter of the 2nd word, followed by the second to last character of the 1st word, followed by the second to last character of the 2nd word and so on. Be sure to use the same format and wording as in the sample run in the table below. You can use the loop of your choice to solve the problem. The box below illustrates how your program should behave and appear. REMEMBER in the output: - is a space and is a new line. Text in green is user input Enter 2. words (same length): 12345 vwxyz The new word is 5z4y3x2w1vd What an odd word! Note 1: You are to expect a perfect user who will always enter 2 words of the same length; that is, do not verify the validity of user input. Note 2: The use of libraries other than java.util.Scanner is prohibited. Your program must work for any strings entered, not just the ones in the samples above. The words can be of any length not just 5 as in the sample above. Note 3: Final thought, remember that your solution is case-sensitive and space-sensitive and fulfill the above instructions carefully and precisely. Reminder: When submitting your solution to the lab system, make sure that if you have a package statement at the top of your .java file it is commented out (has // in front of it) as failing to do so will result in a Compilation Error hence a grade of O (restriction of the PC system

Answer 1

package string;

import java.util.Scanner;

// Defines a class StringTest

public class StringTest

{

// main method definition

public static void main(String s[])

{

// Creates a Scanner class object

Scanner input = new Scanner(System.in);

// Accepts two words

System.out.println("Enter 2 words (same length): ");

String firstWord = input.next();

String secondWord = input.next();

// To store the concatenated string

String newWord = "";

// Checks if first word length is equals to second word length

if(firstWord.length() == secondWord.length())

{

// Loops from last character of the first word to beginning

for(int c = firstWord.length()-1; c >= 0; c--)

{

// Adds the current character of the first word to newWord

newWord += (char)firstWord.charAt(c);

// Adds the current character of the second word to newWord

newWord += (char)secondWord.charAt(c);

}// End of for loop

// Displays the new word after concatenation

System.out.print("\n\n The new word is: " + newWord);

}// End of for loop

// Otherwise two strings are not equal length

else

System.out.print("\n ERROR: Two words are not same length");

}// End of main method

}// End of class

Sample Output 1:

Enter 2 words (same length):
this 1234

The new word is: s4i3h2t1

Sample Output 2:

Enter 2 words (same length):
check 785

ERROR: Two words are not same length
