AP Computer Science Principles taught interactively

Vasundhra guided Darren through the process of setting up the Spire.XLS library in a Java project to create Excel pivot tables. They resolved dependency issues in NetBeans and began coding the pivot table functionality, including setting up the workbook, worksheet, headers, and data range. Vasundhra assigned the remaining pivot table code as homework for Darren to complete before the next session.

Vasundhra taught Vinay how to use Java's Scanner class to take user input for student names and grades. They practiced using `nextLine()` but faced challenges applying it to array input in the online compiler. Homework was assigned to reinforce the concepts.

Vasundhra assisted Vinay in practicing Java array and loop concepts through three coding exercises: reversing an array, printing array elements with their indices, and calculating the sum of the array's elements. Vinay received guidance on loop implementation and debugging. Vasundhra emphasized avoiding previous mistakes in future sessions.

Vasundhra guided Vinay through a coding exercise focused on array manipulation in Java. Vinay worked on methods to check for the existence of a number within an array and to return its index. They debugged his code together, focusing on loop logic and conditional statements.

Vasundhra tutored Vinay on Java arrays, covering creation, access, and limitations (no deletion). She explains direct initialization vs. creating blank arrays. Vinay then completes a coding exercise to sum corresponding elements of two arrays into a third, guided by Vasundhra to use `System.out.print` for output.

Vasundhra guided Vinay in practicing switch blocks in Java by working through a coding problem. Vinay was tasked with creating a method to check if a character is a vowel, consonant, or neither using a switch block. Vasundhra provided real-time debugging assistance and suggestions for code optimization.
