Programming

Class loaders are important for Java programmers, because they can affect how our code runs. We look at the different types of class loaders and how they work.

The rule of three is a simple code refactoring rule. Refactoring is a disciplined way to improve existing code by changing its internal structure without changing its external behaviour.

Yesterday I needed a drop of super glue to fix something. Although I only needed a drop – and I use the tiny 5ml tubes – I still got some on my fingers. Because that’s almost a rule with super glue. It sticks, and that includes your fingers. And it’s

A look at microservices and the scale cube. The scale cube is a model to visualise scaling applications by segmenting and defining microservices.

Cyclomatic Complexity (CC) is one of the metrics we can use to measure code complexity. Lewis looks at how it is calculated and what it means for programmers.

Java assertions are a useful feature of the language. An assertion is a statement that lets us test any assumptions that we have about our code. The Java assert statement helps to reduce buggy code.

Lewis experiments with using AI to write a file walker in Java, with some more elaborate stream processing.

Lewis takes a look at how to use a stream-based approach to walking a file tree.

Lewis looks at how to walk a file tree in Java with the walkFileTree() method and the FileVIsitor interface.

In the final part of this series on memory leaks in Java, Lewis takes a look at the JDK Flight Recorder and JDK Mission Control tools. Together these create a complete tool chain to continuously collect detailed runtime information.
