    Simplified Java Solution Method:

    public static String caesarCipher(String s, int k) {
    // Write your code here
        String cipher = "";
        k%=26;
                
        for(char c : s.toCharArray()){
            if(Character.isLetter(c)){
                if((Character.isUpperCase(c)&&(c+k)>90)||(Character.isLowerCase(c)&&(c+k)>122)){
                     c-=26;                  
                }
                c+=k;
            }
            cipher+=c;   
        }
        return cipher;
    }
