Question

For this lab you are required to fulfill all requirements exactly as described in this provided document, no less, no more. 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

import java.util.Scanner;//it is to take input from the user
public class Main
{
   public static void main(String[] args) {
    String s;//s is first word
    String s1;//s1 is second word
    System.out.println("Enter 2 words (same length):");
    Scanner ob=new Scanner(System.in);//creatin Object for Scanner
    s=ob.nextLine();//taking s from the user
    s1=ob.nextLine();//taking s1 from the user
    char[] ch= s.toCharArray();//converting s to chararray
    char[] ch1 = s1.toCharArray();//converting s1 to chararray
    int n=s.length();
    char[] ch2=new char[n+n];//creating final chararray to store the new word
    int j=n-1;
    int m=n-1;
    for(int i=0;i<(2*n);i++)//iteriting 2*n times
    {
        if(i%2==0)//if even index then procede with ch
            {   ch2[i]=ch[m];
                m--;}
        else//if odd index then procede with ch1
            {
                ch2[i]=ch1[j];
                j--;
              
            }
    }
    System.out.print("The new word is ");
    for (char c : ch2) { //printing the resultant array
            System.out.print(c);
        }
        System.out.print("\nWhat an odd word!");  
    }
}

input Enter 2 words (same length) : 12345 vzxyz The new word is 5z4y3x2zlv What an odd word!
