Reflection is a C# language mechanism for accessing dynamic object properties on runtime. Typically, reflection is used to fetch the information about dynamic object type and object attribute values. In REST application, for example, reflection could be used to iterate through serialized response object.

Remark: According to MS guidelines performance critical code should avoid reflection. See https://msdn.microsoft.com/en-us/library/ff647790.aspx

The collections framework in java.util provides a number of generic classes for sets of data with functionality that can't be provided by regular arrays.

Collections framework contains interfaces for Collection<O>, with main sub-interfaces List<O> and Set<O>, and mapping collection Map<K,V>. Collections are the root interface and are being implemented by many other collection frameworks.

Java I/O (Input and Output) is used to process the input and produce the output. Java uses the concept of stream to make I/O operation fast. The java.io package contains all the classes required for input and output operations. Handling files is also done in java by Java I/O API.

Gradle is a JVM-based build system that enables developers to write high-level scripts that can be used to automate the process of compilation and application production. It is a flexible plugin-based system, which allows you to automate various aspects of the build process; including compiling and signing a .jar, downloading and managing external dependencies, injecting fields into the AndroidManifest or utilising specific SDK versions.

A singleton is a class that only ever has one single instance. For more information on the Singleton design pattern, please refer to the Singleton topic in the Design Patterns tag.

RecyclerView is a more advanced version of List View with improved performance and additional features.

The java.util.Iterator is the standard Java SE interface for object that implement the Iterator design pattern. The java.lang.Iterable interface is for objects that can provide an iterator.
