Set 3

Arithmetic Operator

+ for plus, - for minus, * for multiplication, / for division, and % for modulus.

AND

A binary Boolean operation that results in true only if both boolean values are true, otherwise the result is false.

Default

A command in a switch case statement that serves as the option at the end of the statement which is executed when none of the other cases matched.

Switch Statements (case, switch, and default)

A conditional control structure in programming that functions as a multi-step if else statement, where several cases are stated and examined during execution to seek a match, and then a command is executed when a match is found.

Function

A function in programming is most often a procedure or method that performs a calculation and returns a value of some sort.

Void Method

A method that starts with the word void, which indicates no return value, but designates a process of some sort that occurs.

Return Method

A method which will return a value of some sort, usually after a calculation or process. Typically, the heading of a return method will start with the data type of the value being returned, such as int calc, or string firstName.

Debugging

A methodical process of finding and reducing bugs, defects, or errors in a computer program or a piece of electronic hardware.

Method

A process in Java that can be either a procedure (void method) that performs an action of some sort, or a function (return method) that returns a calculated value.

Procedure

A programming module that performs a task of some sort, like outputting the contents of a data structure, or performing a sort on an array.

Call (method, procedure, function)

A programming statement used to execute a previously defined method, function, or procedure, often sending outside information into the process using parameters

Break

A programming term that ends the process in a control structure, such as a loop or switch case statement.

Error

A situation in a program that indicates a flaw in the source code, either syntax-based (punctuation or grammar), run-time (occurs during execution, such as file not found, or division by zero), or logic based where the program runs but does not produce the desired results.

Conditional Statement

A statement in programming that makes a decision using if or if-else situations by evaluating a boolean condition.

Checked Exceptions

A type of exception (execution error) that a compiler will check for during the compile process, such as the possibility of a file input error, where the code must explicitly indicate how this possible exception will be handled, either by using a "throws" statement, or by using a "try catch" block.

Parameter

A variable located inside the parentheses of a method call or method header.

Binary

A word that is used to describe the base 2 number system.

Integrated Development Environment (IDE)

An application used in programming that combines the source code editing process, compiling and program execution process into one easy-to-use application. Common IDEs for programming include Eclipse, NetBeans, JCreator, and BlueJ.

Syntax Error

An error associated with punctuation, spelling or grammar in a computer program.

Exception

An error in programming that is "thrown" when something bad happens in a program, usually during runtime. In Java, there is a whole family of Exceptions, like IndexOutOf BoundsException or FileNotFoundException. Generally there are two types: checked and unchecked, checked meaning they are checked during compile time, and unchecked when they are thrown during runtime.

Lexical Error

An error in programming that is characterized by the misspelling of a word, or reserved words listed out of order.

Runtime Error

An error that occurs during the execution of a program.

Bug

An error, flaw, failure, or fault in a computer program or system that causes it to produce an incorrect or unexpected result, sometimes called a logic error.

A type of operator that performs a calculation on two operands, such as + or -.

Concatenation

The process of joining two strings of characters into a larger string of characters, an operation often indicate by the plus (+) sign.

Equality Operator

An operator in programming logic that tests whether or not two objects or items of data contain the same value. In many currently used languages, the double equals sign (==) is the symbol for testing equality.

Expression

A set of operands and operations that produce a mathematics based or logic based result. Concatenation, or joining of strings, is also considered an expression.

Integer Division

A division process that results in a whole number answer, discarding or truncating any fractional remainder.

Integer Modulus (Modulus)

A division process that results in a whole number answer representing the remainder of the division process, discarding the actual answer. Indicated by the % sign.

Logical Operators

Binary operators that compare the results of two expressions. The result is either true or false.

NOT

The operation in Boolean logic that indicates negation, or "opposite of" operator A symbol used in mathematical and logical expressions, such as the plus (+) or division (/) sign.

OR

The binary operation in Boolean logic that results in a true value if either or both operands are true.

Order of Operations

The order of precedence of all of the operators in a computational system, such as mathematics (PEMDAS) or logic (NAXO).

Relational Operators

Binary operators that compare two operands. The result is always true or false.

Shift Operators

Bitwise operators in programming which shift the binary bits of a value either to the left or to the right.

Shortcut Operators

If Statements

Statements in programming that check to see if a Boolean expression is true, and executes a "then" statement if so, otherwise does nothing. These are often called "one-way" conditional statements.

If/Else Statements

Statements in programming that check to see if a Boolean expression is true, and executes a "then" statement if so, otherwise executes an "else" statement if the condition is false. These are often called "two-way" conditional statements.

Sequential Processing

The basic control structure in programming where commands are executed one after another, in the order in which they are listed.

Parameter Passing

The process in the source code of a program whereby data is passed from one section of the program to another, using method calls that send actual parameters and method definitions that receive the passed data using formal parameters.

Troubleshooting

The process of debugging a program by detecting and correcting errors in syntax and logic.

Conditional Processing

The process of using if and if-else type statements in a program to make a decision based on a boolean (true/false) condition.

Formal Parameter

This is the parameter that is listed in a method header that receives a value from a method or procedure call, and is only in scope during the execution of the method.

Operators that combine the operation and assignment process into one operation, such as +=, -=, *=or /=.

Unary Operator

Actual parameter

Value or variable used as a parameter in a method call.

Pass by Reference

When a parameter is passed by reference, the memory location originally referred to by the actual parameter is passed to the formal parameter, such that any changes made to the object by the formal parameter also affect the original actual parameter.

Pass by Value

When a parameter is passed by value, any changes made to the formal parameter do NOT affect the actual parameter.

An operator in mathematics or in logic which works on only one operand, such as the negative, positive, or complement operators.

XOR (exclusively OR)
