First-class Functions in C++: Defining & Using First-class Functions
Price on Request
1 hour 10 minutes
While C++ is considered an object-oriented language, it provides support for functional programming, including support for first-class functions in three manners: function pointers, function objects, and lambdas. In this course, discover the complexity of C-style function pointers by creating them and invoking functions through them. Next, learn about the various features and uses of function pointers and how to accept functions as input arguments and return functions from a higher-order function. Finally, examine function objects (functors) and use them to overload the call operator, instantiate objects, and use the overloaded call operator. Upon completion, you'll be able to list the properties of C++ first-class functions, create function pointers, return functions from a higher-order function, and define and invoke a functor.

Functions and Memory in C: Getting Started with Pointers
Price on Request
1 hour 20 minutes
One of the main reasons C retains its relevance after 50 years is the level of interaction between the programmer and the memory which C allows for.

PyCharm is one of the most intuitive and feature-rich integrated development environments (IDEs) available for Python development. Explore some of the important features of this IDE, such as debugging with breakpoints, Python package installation, and customizing syntax highlighting, in this 11-video course. Key concepts covered here include how to install and configure the PyCharm IDE on your system; how to customize syntax highlighting for various source files in Python project and how to minimize typing errors by using the auto-complete feature. Next, learn to apply name changes to variables and functions to all their references; learn the state of an application in the middle of code execution with the use of breakpoints; and use the step into feature to get inside function calls and step over to run them in one go. Finally, learn to pause code execution at a line only under a specified condition; and learn to use the resume button to ensure that code execution only pauses at breakpoints.

Java Database Connectivity (JDBC): An Introduction to JDBC
Price on Request
1 hour 30 minutes
Java Database Connectivity (JDBC) is the Java application programming interface (API) that manages the connection and execution of queries with a database. The focus of this course is to provide you hands-on experience with a variety of JDBC objects that are required to set up a connection to a relational database and run queries against it. Learn how to set up a MySQL database and use DataSource and Data Manager instances to connect to it from your Java application. Delve into objects such as Statements and PreparedStatements that enable you to execute a variety of queries against the database and familiarize yourself with the ResultSet that allows you to parse the results of the execution of a select query. You'll have the foundational knowledge to connect to and query against databases using JDBC objects after completing this course.

Java Database Connectivity (JDBC): Batch Executions & Transactions with JDBC
Price on Request
55 minutes
In scenarios where an application has to issue several updates, performing them in batches greatly benefits performance. A set of updates can then be wrapped in an interaction that either succeeds or fails altogether with the help of transactions in relational databases. Use this course to explore the implementation of advanced database operations using Java Database Connectivity (JDBC), specifically batch executions and transactions. Discover how executions of multiple similar queries can be optimized by aggregating them together in a batch and then executing them together and learn to set up queries to execute as transactions. You will also examine concepts, such as rollbacks, commits, and savepoints, and how these can be implemented using JDBC. You will be able to implement batch executions and transactions in a Java program using JDBC.

Java Database Connectivity (JDBC): Interacting with Databases using RowSets
Price on Request
1 hour 35 minutes
RowSet is a Java Database Connectivity (JDBC) object that holds tabular data in a form that makes it more adaptable and easier to use. Explore how to enable database operations from within your Java application using RowSet type in JDBC with the help of this course. Explore RowSets within JDBC and how they don't just represent the results of query execution, but include methods to connect to and run queries against a database as well. The course will also help you examine JdbcRowSets in detail and distinguish it from CachedRowSets. After finishing the course, you'll have an understanding of RowSets in JDBC and how connected and disconnected RowSets differ from each other.

Java Database Connectivity (JDBC): Joining & Filtering Data with RowSets
Price on Request
1 hour 10 minutes
A CachedRowSet is a Java Database Connectivity (JDBC) RowSet where the rows are cached, and the RowSet is disconnected (i.e., doesn't maintain an active connection to the database). CachedRowSets allow you to work on data without keeping your database connection open all the time. This course will help you get acquainted with specialized implementations of the CachedRowSet - the JoinRowSet and FilteredRowSet - which enable offline joins and data filtering. Discover how to implement join operations using a JoinRowSet and examine the use of a FilteredRowSet in implementing the equivalent of the WHERE clause in a SQL query. You will also explore the use of predicate class in order to achieve this. Upon completion of this course, you'll be able to carry out join and filter operations within a Java program using JDBC JoinRowSets and FilteredRowSets.

Java Web Services: Enabling CRUD Operations with REST APIs
Price on Request
1 hour
Web services for Java applications based on the REST technology provide a normalized and scalable means to set up client communication with external applications. This course demonstrates how to integrate RESTful applications with a relational database so that clients can interact with it and perform create, read, update, and delete (CRUD) operations on it. Learn how to link a MySQL database with a RESTful app. Set it up to respond to a GET request by looking up a table in your database. Advancing from read operations, establish add, update, and delete operations, defining methods that can respond to POST, PUT, and DELETE requests. By the end of the course, you'll be able to facilitate your clients to use your web service app to interact with a database.
