****Using java eclipse please fix my coding for the following problem. My coding starts over when you get to A or Z and we are suppose to "assume that the shift never goes past the beginning or end of the alphabet". So please fix the coding to make it not go before A or after Z.****

Problem: Write a program called CaesarLite that encodes a message using a Caesar cipher. The user should be prompted for the number of positions to shift (positive or negative) and a message to encode. For example, a shift of 3 would map A to D and B to E. You can assume that only capital letters need to be shifted and that other characters will not be changed. For this version, ***you can assume that the shift never goes past the beginning or end of the alphabet.***

Example output 1: Enter shift: 4 Enter message: HELLO Encoded message: LIPPS

Example output 2: Enter shift: -1 Enter message: IbM 9000 Encoded message: HbL 9000

Here is my code for this problem that needs fixing:

import java.util.Scanner;

import java.util.*;

public class CaesarLite {

public static String encode(String[] message1, int shift) {

String s1 = "";

for (int j = 0; j < message1.length; j++) {

String word = message1[j];

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

char c = word.charAt(i);

if (c >= 'A' && c <= 'Z' && (char) (c + shift) >= 'A' && (char) (c + shift) <= 'Z') {

s1 += (char) (c + shift);

} else if ((char) c + shift > 'Z' && c >= 'A' && c <= 'Z') {

s1 += (char) (c - (26 - shift));

} else if ((char) c + shift < 'A' && c > '9' && c >= 'A' && c <= 'Z') {

s1 += (char) (c + (26 + shift));

} else {

s1 += c;

}

}

if (j < message1.length - 1)

s1 += " ";

}

return "The Encoded message is : " + s1;

}

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

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

int shift = sc.nextInt();

sc.nextLine();

System.out.println("Enter the message:");

String[] message = sc.nextLine().split(" ");

System.out.println(CaesarLite.encode(message, shift));

}

}
