In Java, a "default constructor" refer to a nullary constructor that is automatically generated by the compiler if no constructors have been defined for the class or in the absence of any programmer-defined constructors (e.g. in Java, the default constructor implicitly calls the superclass's nullary constructor, then executes an empty body ...

v = [3 x ^ 2 + 2 y ^ 2 for x in 1: 7 for y in 1: 7 if x % y == 0] And just changing square brackets to the round one, we get a generator: g = ( 3 x ^ 2 + 2 y ^ 2 for x in 1 : 7 for y in 1 : 7 if x % y == 0 )
In computer programming, a nullary constructor is a constructor that takes no arguments. [1] Also known as a 0-argument constructor , no-argument constructor , [ 2 ] parameterless constructor or default constructor .
Java's division and modulus operators are well defined to truncate to zero. C++ (pre-C++11) does not specify whether or not these operators truncate to zero or "truncate to -infinity". -3/2 will always be -1 in Java and C++11, but a C++03 compiler may return either -1 or -2, depending on the platform.
The builder pattern is a design pattern that provides a flexible solution to various object creation problems in object-oriented programming.The builder pattern separates the construction of a complex object from its representation.
Generally, var, var, or var is how variable names or other non-literal values to be interpreted by the reader are represented. The rest is literal code. Guillemets (« and ») enclose optional sections.
Here, the list [0..] represents , x^2>3 represents the predicate, and 2*x represents the output expression.. List comprehensions give results in a defined order (unlike the members of sets); and list comprehensions may generate the members of a list in order, rather than produce the entirety of the list thus allowing, for example, the previous Haskell definition of the members of an infinite list.
