我尝试在java中使用分隔符输入使caesar加密。

import java.util.Scanner;

public class CaesarEncryption {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入要加密的字符串：");
        String input = scanner.nextLine();
        System.out.println("请输入分隔符：");
        String delimiter = scanner.nextLine();
        
        String[] words = input.split(delimiter);
        StringBuilder encryptedString = new StringBuilder();
        
        int offset = 3; // 偏移量为3
        
        for (String word : words) {
            for (int i = 0; i < word.length(); i++) {
                char c = word.charAt(i);
                if (Character.isUpperCase(c)) {
                    char encryptedChar = (char) ((c - 'A' + offset) % 26 + 'A');
                    encryptedString.append(encryptedChar);
                } else if (Character.isLowerCase(c)) {
                    char encryptedChar = (char) ((c - 'a' + offset) % 26 + 'a');
                    encryptedString.append(encryptedChar);
                } else {
                    encryptedString.append(c);
                }
            }
            encryptedString.append(" ");
        }
        
        System.out.println("加密后的字符串为：" + encryptedString.toString());
    }
}
