Lombok’s@Builderannotation is a useful technique to implement thebuilder patternthat aims to reduce the boilerplate code. In this tutorial, we will learn to apply @Builder to a class and other useful features. Ensure you have included Lombok in the project andinstalled Lombok support in the I...
Java Builder Pattern with Inheritance (and no ugly casts!) This very small example project details how to support the builder pattern for a Java class hierarchy, by utilizing Java generics. The Problem The builder pattern is useful for building objects that have many properties, avoiding the the...

The below example shows how we can implement the builder pattern in kotlin as follows. We are creating the class name as kot_builder. Code: classkot_builder{privatevarstud_name:String?=nullfunsetName(stud_name:String){this.stud_name=stud_name}fungetName():String?{returnthis.stud_name}}cla...
1. When to use proxy design pattern A proxy object hides the original object and control access to it. We can use proxy when we may want to use a class that can perform as an interface to something else. Proxy is heavily used to implement lazy loading related usecases where we do not...
These patterns are often adopted when attempting to work around perceived or real limitations in Power Apps. While we try to guide you towards the best patterns, it's still possible to unintentionally use a bad pattern, resulting in an app that performs poorly. Four key performance design ...

In this sample we are going thru the most common scenarios using this component. Copy Kernel kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion( modelId: TestConfiguration.OpenAI.ChatModelId, apiKey: TestConfiguration.OpenAI.ApiKey) .Build(); Using Kernel Builder to configure and build ...
Using this pattern, all the implementation is delegated to the attribute, and our Proxy engine is completely decoupled with the many implementations. You can check the relevant parts of the code in the snippet below. Using just a few lines of code, we were able to implement a very powerful...
