Or that there is no proper Forms support on XYZ-os. Or how Visual Studio is slow and a massive memory hog. For every person who waxes lyrical about the joy of working with C# (for example), there are 3 more that will tell you anecdotes about "assembly hell". The paradigms, VMs, IDEs, patterns and practices etc etc.Īnd for the record it's not just Java (it just seems to be more pronounced in the Java-development ecosystem). But, like with many other programming languages out there, you can't really dissociate the language from the environment and everything that goes with it. I have never had significant problems with Java-the-language. Reading these comments, it's strange to see that the "Java" paradigm/context issue still exists after all these years. I honestly believe that the vast majority of people's Java knowledge on Reddit and HN comes from ignorant comments that have been in a self-reinforcing recursive loop for years. However, they can't grasp get it in this context. Reddit and HN are able to grasp that pattern just fine when they are slamming Microsoft. The story of Spring's relationship to Java EE is the classic "embrace, extend, extinguish". However, while it CAN interact with all of those Java EE API's, it doesn't NOT "depend" on them! Spring has extensions that allow it to interface with nearly anything in the Java ecosystem (and its DI container makes it easy to write an integration to anything new). Hibernate won the ORM wars back in the day, and so the Hibernate folks were allowed to write the JPA spec, making it near-identical to the existing Hibernate API. Even JPA itself didn't come out of the "Java EE" world. And that is totally optional, with a handful of newer ORM frameworks seriously eating into its market share. Of that list, a typical Spring Boot application in the wild miiiiiiight use JPA. The most important Java EE specifications (now "Jakarta EE", as "Java EE" hasn't existed for years), are: CDI, EJB, JPA, JTA, JMS, JAX-WS, JAX-RS, JSTL, JSP, and JavaMail. It really is, "Tell me that you know little about Java beyond forum comments that you've read, without telling me that you know little about Java beyond forum comments that you've read". The other method accepts two parameters, a CoffeeSelection, and an int.This take is so exhausting. The first one accepts one parameter of type CoffeeSelection. The BasicCoffeeMachine class implements two methods with the name brewCoffee. Let’s use the same CoffeeMachine project as we used in the previous posts of this series. This approach is called static binding or static polymorphism. That signature allows the compiler to identify which method to call and binds it to the method call. In most cases, each of these overloaded methods provides a different but very similar functionality.ĭue to the different sets of parameters, each method has a different signature. This kind of overloading is not recommended because it makes the API difficult to understand For example, one method accepts a String and a Long and another one accepts a Long and a String. They need to expect the parameters in a different order.The types of the parameters need to be different, one method accepting a String and another one accepting a Long. They need to have a different number of parameters, one method accepting 2 and another one accepting 3 parameters.The parameter sets have to differ in at least one of the following three criteria: But, Java uses a different set of parameters called method overloading and represents a static form of polymorphism. Java, like many other OOP languages, allows you to implement multiple methods within the same class that use the same name. Due to this, all objects in Java are polymorphic because they pass at least two instanceof checks. As described in our post about inheritance, all Java classes extend the class Object. If the object successfully passes multiple is-a or instanceof tests, it’s polymorphic. To know whether an object is polymorphic, you can perform a simple test. Each type can provide its own independent implementation of this interface. In computer science, it describes the concept that you can access objects of different types through the same interface. Polymorphism is one of the core concepts of object-oriented programming (OOP) and describes situations in which something occurs in several different forms. Object-Oriented Programming has different concepts allowing developers to build logical code.
