    en.wikipedia.org/wiki/Three-way_comparison

    Many object-oriented programming languages have a three-way comparison function, which performs a three-way comparison between the object and another given object. For example, in Java, any class that implements the Comparable interface has a compareTo method which either returns a negative integer, zero, or a positive integer, or throws a ...

    C++11 extended this further, to make classes act identically to POD objects in many more cases. ^c pair only ^d Although Perl doesn't have records, because Perl's type system allows different data types to be in an array, "hashes" (associative arrays) that don't have a variable index would effectively be the same as records.

    The Computer Language Benchmarks Game site warns against over-generalizing from benchmark data, but contains a large number of micro-benchmarks of reader-contributed code snippets, with an interface that generates various charts and tables comparing specific programming languages and types of tests.

    Finally, the constructor body is executed. This ensures proper order of initialization, i.e. the fields of a base class finish initialization before initialization of the fields of an object class begins. There are two main potential traps in Java's object initialization. First, variable initializers are expressions that can contain method calls.

  7. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    An object is a data structure or abstract data type containing fields (state variables containing data) and methods (subroutines or procedures defining the object's behavior in code). Fields may also be known as members, attributes, or properties.

    For an example from Java's standard library, java.util.Collections.sort() takes a List and a functor whose role is to compare objects in the List. Without first-class functions, the function is part of the Comparator interface. This could be used as follows.

  9. Comparison of Java and C++ - Wikipedia

    Java only allocates memory via object instantiation. Arbitrary memory blocks may be allocated in Java as an array of bytes. Java and C++ use different idioms for resource management. Java relies mainly on garbage collection, which can reclaim memory, [7] while C++ relies mainly on the Resource Acquisition Is Initialization (RAII) idiom. This is ...
