Question 1

Array

Answer 1

An indexed structure that holds multiple values of the same type.

Question 2

Index

Answer 2

An integer indicating the position of a particular value in a data structure.

Question 3

Zero-based indexing

Answer 3

A numbering scheme used throughout Java in which a sequence of values is indexed starting with 0 (element 0, element 1, element 2, and so on).

Question 4

Auto-initialization

Answer 4

The initialization of variables to a default value, such as on an array’s elements when it is constructed.

Question 5

Array traversal

Answer 5

Processing each array element sequentially from the first to the last.

Question 6

Sequential access

Answer 6

Manipulating values in a sequential manner from first to last.

Question 7

Random access

Answer 7

Manipulating values in any order whatsoever to allow quick access to each value.

Question 8

Value semantics (value types)

Answer 8

A system in which values are stored directly and copying is achieved by creating independent copies of values. Types that use value semantics are called value types.

Question 9

Reference semantics (reference types)

Answer 9

A system in which references to values are stored and copying is achieved by copying these references. Types that use reference semantics are called reference types.

Question 10

null

Answer 10

A Java keyword signifying no object.

Question 11

Multidimensional array

Answer 11

An array of arrays, the elements of which are accessed with multiple integer indexes.
