array single variable that can reference a large collection of of fixed number of data values of a single type
array declaration consists of data type and reference variable
array initializer shorthand notation that consists of data type, reference variable, and a sequence of expressions that are assignment compatible with the element type of the array
array instantiation process of creating an instance of an array through use of the new operator or the process of initialization
binary search process of looking for a specific element in a sorted array by repeatedly dividing the search interval in half
element a single piece of data(value or reference variable) in an array; indexed variable
garbage collection process of reclaiming the run-time unused memory automatically

pre-condition something that must always be true just prior to the execution of some section of code or before an operation in a formal specification
post-condition something that must always be true just after the execution of some section of code or after an operation in a formal specification
reference variable holds the memory location of the real object
selection sort elementary sorting algorithm that finds the smallest element in the array and swaps it with the first element, then finds the next smallest element and swaps it with the second element, and so on.
