import java.util.*; /*This form of importing classes makes all classes in package java.util available by name, could be used instead of the import declaration in the previous example. */ import java.*; /*This statement is legal, but does nothing, since there are no classes directly in package java.

A negative base (or negative radix) may be used to construct a non-standard positional numeral system.Like other place-value systems, each position holds multiples of the appropriate power of the system's base; but that base is negative—that is to say, the base b is equal to −r for some natural number r (r ≥ 2).
Static import is a feature introduced in the Java programming language that allows members (fields and methods) which have been scoped within their container class as public static, to be used in Java code without specifying the class in which the field has been defined.
package strandSort; import java.util.*; public class strandSort {static LinkedList < Integer > solList = new LinkedList < Integer > (); static int k = 0; /** * This is a recursive Strand Sort method. It takes in a linked list of * integers as its parameter. It first checks the base case to see if the * linked list is empty.
In mathematics and computer science, a higher-order function (HOF) is a function that does at least one of the following: . takes one or more functions as arguments (i.e. a procedural parameter, which is a parameter of a procedure that is itself a procedure),
In mathematics, the Lévy C curve is a self-similar fractal curve that was first described and whose differentiability properties were analysed by Ernesto Cesàro in 1906 and Georg Faber in 1910, but now bears the name of French mathematician Paul Lévy, who was the first to describe its self-similarity properties as well as to provide a geometrical construction showing it as a representative ...
With Java 5.0, additional wrapper classes were introduced in the java.util.concurrent.atomic package. These classes are mutable and cannot be used as a replacement for the regular wrapper classes. Instead, they provide atomic operations for addition, increment and assignment. The atomic wrapper classes and their corresponding types are:
