    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.

  4. Three-way comparison - Wikipedia

    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 ...

    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.

    en.wikipedia.org/wiki/Namevalue_pair

    A namevalue pair, also called an attribute–value pair, key–value pair, or fieldvalue pair, is a fundamental data representation in computing systems and applications. Designers often desire an open-ended data structure that allows for future extension without modifying existing code or data.

  9. Object copying - Wikipedia

    en.wikipedia.org/wiki/Object_copying

    In that case a new object B is created, and the fields values of A are copied over to B. [3] [4] [5] This is also known as a field-by-field copy, [6] [7] [8] field-for-field copy, or field copy. [9] If the field value is a reference to an object (e.g., a memory address) it copies the reference, hence referring to the same object as A does, and ...
