Classes and Objects: Object Orientation Philosophy, the state of some data-holding instance like a file or a database. Although this is certainly true, it does not tell the whole story. In real-world scenarios, computer programs exhibit another characteristic: They are supposed to be of some practical use, and as a result of that, model real-world e

Corporeal

Structural Constructs,le to express. This branching happens inside functions, so it imposes some kind of substructuring inside classes and singleton objects. In this chapter we cover such branching constructs, together with auxiliary classes that help us write corresponding code.

不成比例

Exceptions: If Something Goes Wrong,complexity, those built by many developers, or those that use external programs (libraries), the situation is not that clear. Problems will arise, for example, if lists or arrays get addressed out of bounds, some I/O access to files or network data streams fails, or objects end up in an unanticipate

HEED

Data Containers,r belongings, math set theory uses collections for relation formulas, galaxies collect stars, atoms collect elementary particles, and so on. It is thus no surprise that computer languages, intended to model real-world scenarios, must be able to model collections as well.

Using the Java and Kotlin APIs, these a lot to this point. Once in a while we have mentioned and used the term . without explicitly stating what that actually is. In real life a library is a place where much information is available. Whenever you need to know something you can go there and try to find a book that can show you wha

More APIs,and time handling, including transformations between different time representations, and parsing and formatting dates and times, we describe the date and time API. For input and output, which for Android boils down to file handling, we give an overview of the input and output API. For dynamically ac
