Question

Below is the assignment, I have completed and tested every step except for the last one.

"Print aLine with the first 'c' 'C' 'd' or 'D' removed."

any help would be appreciated

ASSIGNMENT

Write a program using Scanner and its nextLine method. The following is an example of how to use nextLine

Scanner kybd = new Scanner(System.in);

System.out.println("Enter a line of text");

String aLine = kybd.nextLine();

If the user's input is shorter than 7 characters, print the message "The input is too short" and do no further processing. If the user's input is 7 characters or longer, perform the following operations.

Print either "the original String has no leading or trailing whitespace" or "the original String has leading or trailing whitespace." (Hint: the trim method will be a good start, but you'll need more.)

Swap the first four and last three characters of aLine and print the result.

Print aLine in all upper case.

Print the compareTo results of comparing aLine in all lower case with the original aLine. (This will be a number.)

Print whether the first half of aLine is the same as the last half of aLine except for case.

Print aLine with the first 'c' 'C' 'd' or 'D' removed.

Note: treat each of these steps as an independent action operating on the original input. So if the original input was

kilroy was here, but not godot

swapping the first four and last three characters would print

dotoy was here, but not gokilr

and printing aLine in all upper case would result in

KILROY WAS HERE, BUT NOT GODOT

You may use ONLY String's indexOf, charAt, length, compareTo, toUpperCase, toLowerCase, trim, equals, equalsIgnoreCase and substring methods.

Grading Elements

• Program checks the length of user input. If it is too short, the program prints a message. If it is sufficiently long, the specified operations are performed.
• Program always uses the original input for each manipulation
• Program uses only the specified String methods for manipulations
• Program prints whether the String has leading or trailing whitespace
• Program tests for any whitespace, not just spaces
• Program swaps the first four and last three characters
• Program prints the input in upper case
• Program prints the results of String's compareTo method pn the original input and the original input converted to lower case
• Program compares the first half and last half of the input, ignoring case
• Program prints the original input with the first 'c' 'C' 'd' or 'D' removed

If you have any doubts, please give me comment...

import java.util.Scanner;

public class StringPlay{

public static void main(String[] args) {

Scanner kybd = new Scanner(System.in);

System.out.println("Enter a line of text");

String aLine = kybd.nextLine();

int cInd = aLine.toLowerCase().indexOf('c');

int dInd = aLine.toLowerCase().indexOf('d');

int firstInd = (cInd<dInd && cInd!=-1)?cInd:dInd;

if(firstInd!=-1)

aLine = aLine.substring(0, firstInd)+aLine.substring(firstInd+1);

System.out.println(aLine);

}

}
