  3. Range (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Range_(computer_programming)

    Another meaning of range in computer science is an alternative to iterator. When used in this sense, range is defined as "a pair of begin/end iterators packed together". [1] It is argued [1] that "Ranges are a superior abstraction" (compared to iterators) for several reasons, including better safety.

  8. Double-checked locking - Wikipedia

    en.wikipedia.org/wiki/Double-checked_locking

    In software engineering, double-checked locking (also known as "double-checked locking optimization" [1]) is a software design pattern used to reduce the overhead of acquiring a lock by testing the locking criterion (the "lock hint") before acquiring the lock. Locking occurs only if the locking criterion check indicates that locking is required.

  9. Security of the Java software platform - Wikipedia

    en.wikipedia.org/wiki/Security_of_the_Java...

    The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.
