    try {// Normal execution path. throw new EmptyStackException ();} catch (ExampleException ee) {// Deal with the ExampleException.} finally {// Always run when leaving the try block (including finally clauses), regardless of whether any exceptions were thrown or whether they were handled. // Cleans up and closes resources acquired in the try block.

  3. Exception handling (programming) - Wikipedia

    en.wikipedia.org/wiki/Exception_handling...

    [60] recover differs from catch in that it can only be called from within a defer code block in a function, so the handler can only do clean-up and change the function's return values, and cannot return control to an arbitrary point within the function. [61] The defer block itself functions similarly to a finally clause.

    Social pressure is a major influence on the scope of exceptions and use of exception-handling mechanisms, i.e. "examples of use, typically found in core libraries, and code examples in technical books, magazine articles, and online discussion forums, and in an organization’s code standards". [10]

  5. Control flow - Wikipedia

    en.wikipedia.org/wiki/Control_flow

    For non-strict functional languages, functions and language constructs exist to achieve the same result, but they are usually not termed control flow statements. A set of statements is in turn generally structured as a block, which in addition to grouping, also defines a lexical scope.

  6. Error correction code - Wikipedia

    en.wikipedia.org/wiki/Error_correction_code

    A convolutional code that is terminated is also a 'block code' in that it encodes a block of input data, but the block size of a convolutional code is generally arbitrary, while block codes have a fixed size dictated by their algebraic characteristics. Types of termination for convolutional codes include "tail-biting" and "bit-flushing".

    en.wikipedia.org/wiki/PHP_syntax_and_semantics

    Prior to PHP version 5.3.0, functions are not first-class functions and can only be referenced by their name, whereas PHP 5.3.0 introduces closures. [35] User-defined functions can be created at any time and without being prototyped. [ 35 ]

    The TDD steps vary somewhat by author in count and description, but are generally as follows. These are based on the book Test-Driven Development by Example, [6] and Kent Beck's Canon TDD article. [8] 1. List scenarios for the new feature List the expected variants in the new behavior.

  9. GNU Octave - Wikipedia

    en.wikipedia.org/wiki/GNU_Octave

    Octave programs consist of a list of function calls or a script. The syntax is matrix-based and provides various functions for matrix operations. It supports various data structures and allows object-oriented programming. [26] Its syntax is very similar to MATLAB, and careful programming of a script will allow it to run on both Octave and ...
