Consider the following Groovy code. class Product { String sku String description BigDecimal price } Now let's put the Product class into use as follows. Product book1 = new Product(sku: 'P101', description: 'Effective Java', price: 599.0) Product book2 = new Product(sku: 'P101', description: 'Effective Java', price: 599.0) println book1 == book2…
Back in 2015, Gradle introduced this feature which they called 'continuous build'. Those days, I was exploring Ratpack, and it was the first toolkit/ framework to leverage the continuous build feature. The idea here is to rerun the tasks whenever there is a code change. Gradle will first run the…
In a previous post, we used io.micronaut.http.client.BlockingHttpClient to get response from an HTTP endpoint. We used the exchange method as follows. HttpResponse response = client.toBlocking().exchange("/greeting", String) If you are using Java instead of Groovy, you will pass "String.class" instead of "String".We had…
If you are already familiar with Groovy, you know that Groovy supports script mode where you can write Groovy code without explicitly creating a class. This mode is suitable when you want to house the entire code in a single class. If you are new to Groovy, you might want…
Let's start with a Java program! What do you think the following program would print? float price = 0.1f; float amount = 0f; for (int i = 0; i < 10; i++) { amount += price; } System.out.println("Total price: " + amount); Well, the developer indeed intended the amount to have a value of…
In one of my previous posts, I mentioned how I was using the Java syntax of lambda expressions while I was programming with Kotlin. In my observation, whenever we are working on something, if our brain finds a match to what we already know, often end up using the same…
Both Java and Kotlin support lambda expressions. There are similarities in their syntax, though they are precisely not the same. Many of you may be using both languages at work. When you use multiple languages, the syntax of another language may peek in. In my example, after using Groovy for…
A few weeks ago, when I was checking for the versions of a tool on SDKMAN CLI, I noticed the broadcast message that a Micronaut 2 is available. If you are not familiar with SDKMAN already, you may want to take a look at my post on SDKMAN I installed…
Did you ever have to work with multiple Java projects and each of them was on different version Java or any JVM tools? SDKMAN is a CLI tool for managing multiple versions of Java and JVM tools. I started using this tool in its earlier form known as GVM(Groovy…
