| Term | Definition |
|---|---|
| coodinate | variable that specifies a location in a 2 dimensional graphical window |
| traverse | to iterate through all the elements of a set performing a similar operation on each |
| instance | an example from a category. Every object is an instance of some class |
| awt | the Abstract Window Toolkit, one of the biggest and most commonly used packages in Java |
| exception | a run-time error |
| index | a variable or value used to select one of the members of an ordered set, like a character from a string |
| object | collection of related data that comes with a set of methods that operate on it |
| counter | a variable used to count something, usually initialized to zero and then incremented |
| current object | the object on which an object method is invoked. Inside the method, the current object is referred to as this |
| object method | a method that is involved on an object, and that operates on that object. Object methods do not have the keyword static |
| pixel | unit in which coordinates are measured |
| explicit | anything that is spelled out completely |
| bounding box | a common way to specify the coordinates of a rectangular area |
| package | a collection of classes |
| implicit | anything that is left unsaid or implied |
| class method | a method with the keyword static |
| instance variable | a variable defined in a class for which each instantiated object of the class has a separate copy |
| reference | a value that indicates an object |
| aliasing | the condition when 2 or more variables refer to the same object |
| garbage collection | the process of finding objects that have no references and reclaiming their storage space |
| state | a complete description of all the variables and objects and their values at a given point during the execution of a program |
| state diagram | a snapshot of the state of a program shown graphically |
| throw | cause an exception |
| stack trace | a report that shows the state of a program when an exception occurs |
| prototype | the first line of a method |
| increment | increase value by one |
| decrement | decrease value by one |
| body | statements inside the loop |
| loop | a statement that executes repeatedly while some condition is satisfied |
| infinite loop | loop whose condition is always true |
| iteration | one pass through the loop |
| encapsulate | to divide a large complex program into components and isolate components from each other |
| local variable | variable that is declared inside a method and that only exists within that method |
| generalize | to replace something unnecessarily specific with something appropriately general |
| program development | a process to writing programs |
| return type | the part of a method declaration that indicates what type of value the method returns |
| return value | the value provided as the result of a method invocation |
| dead code | part of code that can never be executed |
| scaffolding | code that is used during program development but is not part of the final version |
| void | a special return type that doesn't return a value |
| overloading | having more than one method with the same name but different parameters |
| boolean | a type of variable that can only return true or false |
| flag | a variable that records a condition or status information |
| conditional operator | an operator that compares two values and produces a boolean |
| logical operator | an operator that combines boolean values and produces boolean values |
| modulus | an operator that works on integers and yields the remainder when one number is divided by another |
| chaining | a way of joining several conditional statements in sequence |
| nesting | putting a conditional statement inside one or both branches of another conditional statement |
| typecast | an operator that converts from one type to another |
| recursion | the process of invoking the same method you are currently executing |
| base case | a condition that causes a recursive method not to make a recursive call |
| initialization | a statement that declares a new variable and assigns a value to it at the same time |
| floating point | a type of variable that can contain fractions as well as variables |
| class | a collection of methods |
| method | a named sequence of statements that performs a useful function |
| parameter | a piece of information in a method requires before you can run it |
| argument | a value that you provide when you provide a method |
| frame | a structure that contains a methods parameters and variables |
| invoke | cause a method to execute |
| variable | a named storage location for values |
| value | a number or string that can be stored in a variable |
| type | a set of values |
| keyword | a reserved word used by the compiler to parse programs |
| declaration | a statement that creates a new variable and determines its type |
| assignment | a statement that assigns a value to a variable |
| expression | a combination of variables, operators, and values |
| operator | a symbol that represents a computation like addition, multiplication, or string concatenation |
| operand | one of the values on which an operator operates |
| precedence | the order in which the operands are evaluated |
| concatenate | to join two operands end to end |
| source code | a program in a high level language before being compiled |
| object code | the output of the compiler |
| byte code | special kind of code used for Java |
| statement | a part of a program that specifies a computation |
| library | a collection of class and method definitions |
| bug | an error in the program |
| syntax | the structure of a program |
| semantics | the meaning of a program |
