  2. FindBugs - Wikipedia

    en.wikipedia.org/wiki/FindBugs

    [2] [3] Potential errors are classified in four ranks: (i) scariest, (ii) scary, (iii) troubling and (iv) of concern. This is a hint to the developer about their possible impact or severity. [4] FindBugs operates on Java bytecode, rather than source code. The software is distributed as a stand-alone GUI application.

  3. Unreachable code - Wikipedia

    en.wikipedia.org/wiki/Unreachable_code

    Detection of unreachable code is a form of control flow analysis to find code that can never be reached in any possible program state. In some languages (e.g. Java [9]) some forms of unreachable code are explicitly disallowed. The optimization that removes unreachable code is known as dead code elimination.

  4. Exception handling (programming) - Wikipedia

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

    Versioning: A method may be declared to throw exceptions X and Y. In a later version of the code, one cannot throw exception Z from the method, because it would make the new code incompatible with the earlier uses. Checked exceptions require the method's callers to either add Z to their throws clause or handle the exception.

    ECLAIR – Uses formal methods-based static code analysis techniques such as abstract interpretation and model checking combined with constraint satisfaction techniques to detect or prove the absence of certain run time errors in source code. ESC/Java and ESC/Java2 – Based on Java Modeling Language, an enriched version of Java

  6. Exception handling - Wikipedia

    en.wikipedia.org/wiki/Exception_handling

    Common exceptions include an invalid argument (e.g. value is outside of the domain of a function), [5] an unavailable resource (like a missing file, [6] a network drive error, [7] or out-of-memory errors [8]), or that the routine has detected a normal condition that requires special handling, e.g., attention, end of file. [9]

  7. Exception handling syntax - Wikipedia

    en.wikipedia.org/wiki/Exception_handling_syntax

    This can happen in multi-threaded environments, or even in single-threaded environments when other code (typically called in the destruction of some object) resets the global variable before the checking code. The following example shows a way to avoid this problem (see [dead link ‍] or ; cf. ). But at the cost of not being able to use return ...

  8. Lint (software) - Wikipedia

    en.wikipedia.org/wiki/Lint_(software)

    Lint is the computer science term for a static code analysis tool used to flag programming errors, bugs, stylistic errors and suspicious constructs. [1] The term originates from a Unix utility that examined C language source code. [2] A program which performs this function is also known as a "linter".

  9. Assertion (software development) - Wikipedia

    en.wikipedia.org/wiki/Assertion_(software...

    In computer programming, specifically when using the imperative programming paradigm, an assertion is a predicate (a Boolean-valued function over the state space, usually expressed as a logical proposition using the variables of a program) connected to a point in the program, that always should evaluate to true at that point in code execution.
