Java

Assignment

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).

Then create a new Java application called "BackwardsStrings" (without the quotation marks) that:

Prompts the user at the command line for one 3-character string.

Then (after the user inputs that first 3-character string) prompts the user for another 3-character string.

Then prints out the two input strings with a space between them.

Finally prints on a separate line the two input strings 'in reverse' (see example below) with a space between them.

So, for example, if the first string is 'usr' and the second string is 'bin', your program would output something like the following:

Note that the reversed SECOND string comes FIRST when printing the strings in reverse.

my result

        Scanner input = new Scanner(System.in);
    // read strings
        first=input.nextLine();
        second=input.nextLine();
    // print out the input strings
    System.out.println("The two string you entered are:"+ first+" "+second+".");
    // reverse the strings
        for ( int i=first.length()-1;i>=0; i--)
            firstReversed.append(first.charAt(i));
        for ( int i=second.length()-1;i>=0; i--)
            secondReversed.append(second.charAt(i));
// print out the reverse string
    System.out.println("The two strings in reverse are:"+secondReversed+" "+ firstReversed+ ".");

  
}
}

usr bin
usr bin
The two string you entered are:usr bin usr bin.
The two strings in reverse are:nib rsu nib rsu.
BUILD SUCCESSFUL (total time: 20 seconds)

I am not getting the same output as an the example shown actually i had to type twice to get the result.

please help

Explanation / Answer

Hi

I have modified the code and highlighted the code changes below

BackwardsStrings.java

import java.util.Scanner;
public class BackwardsStrings {

public static void main(String[] args) {
//variables
String first, second;
// TODO code application logic here
StringBuilder firstReversed= new StringBuilder();
StringBuilder secondReversed= new StringBuilder();
Scanner input = new Scanner(System.in);
// read strings
first=input.next();
second=input.next();
// print out the input strings
System.out.println("The two string you entered are:"+ first+" "+second+".");
// reverse the strings
for ( int i=first.length()-1;i>=0; i--)
firstReversed.append(first.charAt(i));
for ( int i=second.length()-1;i>=0; i--)
secondReversed.append(second.charAt(i));
// print out the reverse string
System.out.println("The two strings in reverse are:"+secondReversed+" "+ firstReversed+ ".");

  
}
}

Output:

usr bin
The two string you entered are:usr bin.
The two strings in reverse are:nib rsu.
