  2. Comparison of programming languages (string functions)

    en.wikipedia.org/wiki/Comparison_of_programming...

    String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.

    The C and Java implementations below have a ⁠ ⁠ space complexity (make_delta1, makeCharTable). This is the same as the original delta1 and the BMH bad-character table . This table maps a character at position ⁠ i {\displaystyle i} ⁠ to shift by ⁠ len ⁡ ( p ) − 1 − i {\displaystyle \operatorname {len} (p)-1-i} ⁠ , with the last ...

  4. String (computer science) - Wikipedia

    en.wikipedia.org/wiki/String_(computer_science)

    Files and finite streams may be viewed as strings. Some APIs like Multimedia Control Interface , embedded SQL or printf use strings to hold commands that will be interpreted. Many scripting programming languages , including Perl, Python , Ruby, and Tcl employ regular expressions to facilitate text operations.

  5. Method (computer programming) - Wikipedia

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

    A method in object-oriented programming (OOP) is a procedure associated with an object, and generally also a message. An object consists of state data and behavior; these compose an interface, which specifies how the object may be used. A method is a behavior of an object parametrized by a user.

  6. Immutable object - Wikipedia

    In Java [5]: 84 these are StringBuffer and StringBuilder (mutable versions of Java String) and in .NET this is StringBuilder (mutable version of .Net String). Python 3 has a mutable string (bytes) variant, named bytearray. [6] Additionally, all of the primitive wrapper classes in Java are immutable.

  7. Knuth–Morris–Pratt algorithm - Wikipedia

    en.wikipedia.org/wiki/Knuth–Morris–Pratt...

    In computer science, the Knuth–Morris–Pratt algorithm (or KMP algorithm) is a string-searching algorithm that searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next match could begin, thus bypassing re-examination of previously matched characters.

  8. Java (programming language) - Wikipedia

    en.wikipedia.org/wiki/Java_(programming_language)

    Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. [17]

  9. Regular expression - Wikipedia

    en.wikipedia.org/wiki/Regular_expression

    Algebraic laws for regular expressions can be obtained using a method by Gischer which is best explained along an example: In order to check whether (X+Y) * and (X * Y *) * denote the same regular language, for all regular expressions X, Y, it is necessary and sufficient to check whether the particular regular expressions (a+b) * and (a * b ...
