Elementary Programming
| Term | Definition |
|---|---|
| algorithm | describes how a problem can be solved by listing the actions need to be taken and the order of their execution |
| assignment operator (=) | designates a value for a variable |
| assignment statement | used for storing a value in a variable |
| byte type | 8-bit signed data type for integers |
| casting | an operation that converts a value of one data type to a value of another data type |
| constant | an identifier that represents a permanent value |
| data type | kind of data stored in a variable |
| declare variables | specifying data types and naming a storage location for them |
| decrement operator (--) | subtracts one from the operand |
| double type | 64-bit IEEE 754 data type for floating-point numbers |
| expression | computation involving values, variables, and operators that are evaluates to a value |
| final keyword | required for creating a constant |
| float type | 32-bit IEEE 754 data type for floating-point numbers |
| floating-point number | real numbers; numbers with decimal points |
| identifier | names that identify elements such as classes, methods, and variables in a program |
| increment operator (++) | adds one to the operand |
| incremental code and testing | implementing one at a time |
| int type | 32-bit signed data type for integers |
| IPO | input, process, output |
| literal | a constant value that appears directly in a program |
| long type | 64-bit signed data type for integers |
| narrowing a type | casting a type with a large range to a type with a smaller range |
| operands | values operated on |
| operator | symbol to indicate operation to perform |
| overflow | when a variable is a assigned a value too large in size to be stored in its data type |
| postdecrement | decrement occurs after the rest of the expression is evaluated |
| postincrement | increment occurs after the rest of the expression is evaluated |
| predecrement | decrement occurs before the rest of the expression is evaluated |
| postincrement | increment occurs before the rest of the expression is evaluated |
| primitive data type | simple data types provided by Java; can store only one piece of data at time |
| pseudocode | natural language mixed with some programming code |
| requirements specification | formal process that seeks to understand the problem the software will address and to document in detail what the software system needs to do |
| scope of a variable | part of a program where a variable can be referenced |
| short type | 16-bit signed data type for integers |
| specific import | a single class in the import statement |
| system analysis | seeks to examine methodically the data flow and to identify the system's input and output |
| system design | breaking problem down into manageable components and create strategies for implementing each component |
| underflow | when a floating-point number is too small(too close to zero) to be stored |
| UNIX epoch | time elapsed since midnight January 1, 1970 GMT |
| variable | represents a value stored in memory |
| widening a type | casting a type with a small range to a type with a larger range |
| wildcard import | a package import |
