In the Java API this identity is represented by an instance of can access it by using the MyObject.class expression.Įvery created object gets a reference to this identity, accessible through the Object.getClass() method. The class with all its methods is loaded into memory and receives a unique identity. Simplified, you can think of a class as a collection of methods that receive “this” as the first argument.

The problem with reloading Java codeĪll Java code is associated with methods contained in classes. In reality, achieving this is way more complicated than it sounds. This way, when the JVM accesses the classes or objects of the changed classes next time, new code would already be in there. It would be much faster and easier if we could just reload the classes in the JVM with the new class definitions. Building, packaging and deploying is not necessary - rather an artifact of the platform than a necessity. Two of these phases are irrelevant to implementing the changes. You typically need to build your project, either fully or partially, tear down and restart the Java process running your code and load or deploy your application again. The problem is that the latter can take quite some time, especially with the Java stack.
To implement a change in the app, you first need to code it up, then run the application and verify that the changes you just implemented are actually what you wanted them to be - functionally correct and working. The same is generally true for any technology stack. When dealing with Java application development, you go through several actions over and over again.
