|
Asynchronous |
|
1) Not occurring at the same moment in time as some specific operation of the computer2) In other words, not synchronized with the program's actions |
| |
|
Boolean Expression |
|
A sequence of identifiers, separated by compatible operators, that evaluates to either true or false |
| |
|
Bytecode |
|
A standard machine language into which Java source code is compiled |
| |
|
Case Sensitive |
|
1) Uppercase and lowercase letters are not considered the same2) Two identifiers with the same spelling but different capitalization are considered to be two distinct identifiers |
| |
|
Class (Implementation Phase) |
|
A pattern for an object |
| |
|
Compiler |
|
A program that translates a high-level language program into machine code |
| |
|
Control Structure |
|
An instruction that determines the order in which other instructions in a program are executed |
| |
|
Data Type |
|
A description of the set of values and the basic set of operations that can be applied to values of the type |
| |
|
Declaration |
|
A statement that associates an identifier with a variable, an action, or some other entity within the language that can be given a name so that the programmer can refer to that item by name |
| |
|
Encapsulation |
|
1) Bundling data and actions so that the logical properties of data and actions are separated from the implementation details2) A language feature that enforces information hiding |
| |
|
Fields |
|
1) Named items in a class2) Can be data or subprograms |
| |
|
Inheritance |
|
A mechanism by which one class acquires the properties-data fields and methods-of another class |
| |
|
Instantiate |
|
To create an object from a class |
| |
|
Interpreter |
|
A program that inputs a program in a high-level language and directs the computer to perform the actions specified in each statement |
| |
|
Method |
|
A named algorithm that defines one aspect of the behavior of a class |
| |
|
Object |
|
1) A collection of data values and associated operations2) An entity or thing that is relevant in the context of a problem |
| |
|
Object (implementation phase) |
|
An instance of a class |
| |
|
Object (problem-solving phase) |
|
An entity or thing that is relevant in the context of a problem |
| |
|
Object class (class) |
|
A description of a group of objects with properties (data) and behaviors (actions) |
| |
|
Object class (class)(problem-solving phase) |
|
A description of a group of objects with similar properties and behaviors |
| |
|
Polymorphism |
|
The ability of a language to have duplicate method names is an inheritance hierarchy and to apply the method that is appropriate for the object to which the method is applied |
| |
|
Reserved Word |
|
1) A word in a language that has special meaning2) It cannot be used as an identifier |
| |
|
Strong Typing |
|
Each variable is assigned a type, and only values of that type can stored in the variable |
| |
|
Brainstorming |
|
The stage in which we make a first pass at determining the classes in the problem |
| |
|
Scenarios |
|
The stage in which the behavior of each class is determined |
| |
|
Filtering |
|
The stage in which we go back over the proposed classes determined in the brainstorming stage to see if any can be combined or if any are missing |
| |
|
Responsibility Algorithms |
|
The last stage in which the algorithms are written for the responsibilities for each of the classes |
| |
