Managing Out-of-Memory Data

This section takes you through the APIs you need to access your data that lives outside of your application, typically on the network or on a disk. It covers the Java I/O API and the Foreign Function and Memory API from Project Panama.

  1. The Java I/O API

    Access external resources with the Java Input / Output API.

  2. Common I/O Tasks in Modern Java

    This article focuses on tasks that application programmers are likely to encounter, particularly in web applications, such as reading and writing text files, reading text, images, JSON from the web, and more.

  3. The Foreign Function and Memory API

    The Foreign Function and Memory (FFM) API facilitates Java programs to interoperate with code and data outside the Java runtime without the brittleness and danger of JNI.
