Computer Science and Databases made engaging and supportive

Vasundhra taught Vinay about arrays, explaining they store multiple values of the same data type under one variable, unlike regular variables. She demonstrated array creation, accessing elements via index (starting at zero), and printing values individually and with loops. Vinay then completed a coding exercise, creating and printing an integer array with Vasundhra's help.

Vasundhra guided Darren through adding and formatting tables in PDFs using iText. Darren practiced adding cells, setting background colors, implementing borders, and adjusting text alignment. Vasundhra assigned additional exercises on adding images and lists to tables for Darren to complete before their next session on Thursday.

Vasundhra taught Vinay how to use nested `while` and `for` loops in Java to print dynamic patterns of asterisks and hashes. Vinay practiced writing code to generate these patterns, with Vasundhra providing guidance and correcting errors. They discussed the importance of dynamic code and using loops for flexible solutions.

Vasundhra instructed Vinay on the usage of while loops in Java, differentiating them from for loops and explaining their syntax. Vinay practiced writing while loops to print specific number ranges and began working on a nested while loop to print an asterisk pattern. Vasundhra provided code snippets and guidance to aid Vinay in completing the exercises.

Vasundhra tutored Aarush on Java for loops, covering syntax and logic through exercises like reversing numbers and calculating sums. Aarush initially struggled but improved with guidance, ultimately writing a method to sum even numbers.

Vasundhra taught Darren how to use the iText PDF library in Java to create PDF documents, add pages, paragraphs, and lists, and customize text properties like font and color. Darren practiced adding these elements to a PDF and was assigned a practice problem to work on over the weekend. They agreed to review his work in the next session and continue learning about adding images, tables, and borders.
