INDEXHEAD: Glossary of terms

addition binary infix operator

An operator that adds its two operands together and returns the sum.

assignment binary infix operator

An operator that assigns its rightmost operand to its leftmost operand.

binary operator

An operator that takes two operands.

bit-wise AND binary infix operator

An operator that ANDs the corresponding bits of its two operands together and returns the result.

bit-wise complement unary prefix operator

An operator that flips the bits of its operand and returns the result.

bit-wise exclusive OR binary infix operator

An operator that exclusive ORs the corresponding bits of its two operands together and returns the result.

bit-wise inclusive OR binary infix operator

An operator that inclusive ORs the corresponding bits of its two operands together and returns the result.

bit-wise shift left binary infix operator

An operator that shifts the bits of its leftmost operand left according to the number of positions specified by its rightmost operand and returns the result.

bit-wise shift right with sign extension binary infix operator

An operator that shifts its leftmost operand's bits right by the number of positions specified by its rightmost operand and then returns the result.

bit-wise shift right with zero extension binary infix operator

An operator that shifts the leftmost operand's bits right by the number of positions specified by its rightmost operand and returns the result.

Boolean AND binary infix operator

An operator that ANDs the Boolean values of its two operands together and returns the Boolean result.

Boolean exclusive OR binary infix operator

An operator that exclusive ORs the Boolean values of its two operands together and returns the Boolean result.

Boolean inclusive OR binary infix operator

An operator that inclusive ORs the Boolean values of its two operands together and returns the Boolean result.

Boolean NOT unary prefix operator

An operator that flips the Boolean value of its operand and returns the Boolean result.

cast unary prefix operator

An operator that converts the operand's data type to a specified data type.

conditional ternary operator

An operator that chooses one of two operands.

division binary infix operator

An operator that divides its leftmost operand by its rightmost operand and returns the quotient.

expression

A sequence of operators and operands -- constructed according to the Java language's syntax -- that evaluates to a specific data type's single value.

infix operator

An operator that is situated between its operands.

logical AND binary infix operator

An operator that ANDs the Boolean values of its two operands together and returns the Boolean result.

logical OR binary infix operator

An operator that inclusive ORs the Boolean values of its two operands together and returns the Boolean result.

modulus binary infix operator

An operator that divides its leftmost operand by its rightmost operand and returns the remainder.

multiplication binary infix operator

An operator that multiplies its operands together and returns the product.

negation unary prefix operator

An operator that negates the value of its operand and then returns the result.

operands

Data items that serve as arguments to an operator.

operator

A combination of characters that identifies a data operation, such as addition.

postdecrement unary prefix operator

An operator that returns the value of its operand prior to subtracting 1 from it.

postfix operator

An operator that trails its operand.

postincrement unary postfix operator

An operator that returns the value of its operand prior to adding 1 to it.

precedence

An evaluation order in which certain operators evaluate their operands before other operators do.

predecrement unary prefix operator

An operator that subtracts 1 from its operand and then returns the result.

prefix operator

An operator that precedes its operand.

preincrement unary prefix operator

An operator that adds 1 to its operand and then returns the result.

reference data type checking binary infix operator

Determines whether an object is a class instance.

relational equal to binary infix operator

Returns true if its leftmost operand's numeric value is equal to its rightmost operand's numeric value; otherwise it returns false.

relational greater than binary infix operator

Returns true if its leftmost operand's numeric value is greater than its rightmost operand's numeric value; it returns false otherwise.

relational greater than or equal to binary infix operator

Returns true if the numeric value of its leftmost operand is greater than or equal to the numeric value of its rightmost operand; otherwise it returns false.

relational less than binary infix operator

Returns true if the numeric value of its leftmost operand is less than the numeric value of its rightmost operand.

relational less than or equal to binary infix operator

Returns true if its leftmost operand's numeric value is less than or equal to its rightmost operand's numeric value; otherwise it returns false.

relational not equal to binary infix operator

Returns true if its leftmost operand's numeric value is not equal to its rightmost operand's numeric value; it returns false otherwise.

string concatenation binary infix operator

Concatenates its rightmost operand to its leftmost operand.

subtraction binary infix operator

An operator that subtracts its rightmost operand from its leftmost operand and returns the difference.

ternary operator

An operator that takes three operands.

unary operator

An operator that takes one operand.

unary plus unary prefix operator

An operator that returns its operand.
