# What is Java Development Kit (JDK)?
The core class type included in Java is called the JDK. It includes all the basic tools we would need in a modern application, including everything from collection types and queues, to web sockets, to files and image processing.

As an object-oriented language, methods and properties are organized into classes that are organized in packages. Each Java class should be defined in one file named for that class. The classes under `java.lang`, such as `String`, are always available. Otherwise, we would need to explicitly import the classes using an import statement at the top of our Java file. An instance of a class is called an **object**. All objects are passed by value. Unlike in C, we cannot modify a reference pointer.


A particular aspect of Java is that there are special types called **primitives**. Unlike objects, primitives do not have methods and always have a value. In other words, they can never be `null`.
