Very nice tutorial. It is a pity you stopped doing them. A lot of tutorials with low quality, even those from Xojo itself. Come back!

Why do you use a watermelon as an intro? Pls change it

*Promo sm*

thank you so much, i was strugglingfor 3 days to solve the connection problems...😇

CREATE TABLE Worksfor( E_id Number(1) REFERENCES Employee(E_ID), D_id Number(2) REFERENCES Department(D_ID) Salary Number(6), primary key (E_ID, D_ID) ); Mine keeps showing an Error. What to do, please?

Is there anyway to get in contact with you regarding a coding project based off of one of your tutorials?

Thank you your videos are very helpful 🙏🏻🩷

I know this is an older video, but did you open a script to add tables to, or is this a new script?

Your Apex Oracle videos are TOP NOTCH! This one on joins is fantastic. Thank you!!

where can you check relations between these tables?

Excellent, thank you

These are wonderful videos!!!

i cant find, page not found

Thank you so much

how do you keep the case of the letter and codify it as the same time?

THANKYOU SO MUCH. THE VIDEO WAS SOOOO SOOO HELPFULL . I HAVE REALLY GOOD UNDERSTANDING OF THE TOPIC NO NOW> I WAS SO CONFUSED BEFORE !

love you sir

I like this guy

Best Teacher Ever!!!!

Amazing Video👍🏾👍🏾

Thank you for a helpful tutorial.

Good explanation. This can be a confusing aspect of learning Java for beginners . . . .

my decoding doesn't work. It returns a single character multiple times.

Please guide me to SQL normalization examples video? Thanks

23:57 then this is the result how can i fix it ? Connection Failed java.lang.ClassNotFoundException: org.sqlite.JBDC i already installed the mysqlite jbdc

thank you sir

How do you put decimal? For example 1500.00 and still have the decimal value shown

Thanks for this series! All the videos are super helpful

Thanks so much for this video - I am struggling to figure out SQL in my class and these videos really assisted in my understanding.

I'm grateful for this. Its working without any errors.

Is (% 26) really necessary in decoding method?. (charIndex - Key) will never be greater than 26 and you have the if-statement that will fix if newIndex is negative number.

Hello everyone, Thanks a lot for this lesson!! I updated the encryption part a little, because we have to consider the cases regarding uppercase letters and special characters. So, without to convert the plainText string in lowercase, this is the new encryption part (tested with success in HackerRank): public static String caesarCipher(String plainText, int shift) { String alphabet = "abcdefghijklmnopqrstuvwxyz"; String encryptedText = ""; for (int i = 0; i < plainText.length(); i++) { if (Character.isLetter(plainText.charAt(i))) { if (Character.isUpperCase(plainText.charAt(i))) { int charIndex = alphabet.indexOf(Character.toLowerCase(plainText.charAt(i))); int newIndex = (charIndex + shift) % 26; char encryptedChar = Character.toUpperCase(alphabet.charAt(newIndex)); encryptedText += encryptedChar; } else { int charIndex = alphabet.indexOf(plainText.charAt(i)); int newIndex = (charIndex + shift) % 26; char encryptedChar = alphabet.charAt(newIndex); encryptedText += encryptedChar; } } else { encryptedText += plainText.charAt(i); } } return encryptedText; } Hoping to be useful for everyone.

Thank you very much.

thnks

Hi I am using intelij IDEA to run the code and it is showing no values for the cipher text and decoded message. What can be the problem.

Thanks very much for this enlightening tutorial. I've tried this a few different ways but this is the simplest and by far the most foolproof.

it says database locked, what could be causing this error

How to get only column names

What is the problem ? I typed exactly what you had typed. But error occurs every time. CREATE TABLE Worksfor ( E_ID Number(1) REFERENCES(E_ID), D_ID Number(2) REFERENCES(D_ID), Salary Number(6), Primary key(E_ID,D_ID) );

This is brilliant. Exactly the tutorial I was looking for - thank you.

Its very useful dear. would you please shjow us video tutorial 3. its really same with 4.

i want to rename a specific name in my table what will be the command for that?

Very well explained!!! Thank you!

Hi Sir , your reference link for ALTER table is same with the link for update table

u are wonderful. keep it up.

Best video I've watcted about Joins, thank you so much.

sir everything is fine except the log in , it doesn't work but there is no error message ( the exit button is working , the connection to the data base is working too except the log in)

thank you very much !!! you helped me a lot thanks

Hi, i tried to run the same code on bluej and each time I enter a string and a key, it gives a string out of bounds exception, why is that happening?
