Java Control Structures and Logical Operators

This set covers the fundamental definitions and logic of conditional statements and operators based on the lecture notes.

if

A control structure that evaluates if a specific condition is true, translating to: 'If this IS true, do this…'

else

A block of code that executes when the previous conditions are not met, translating to: 'If the above was NOT met, then do this other thing…'

if-else execution rule

Considered as two opposite paths that never execute at the same time; only one of the two is ever executed.

$$==$$

A comparison operator that translates to 'equal to'.

$$!=$$

A comparison operator that translates to 'different from'.

$>$ / $<$

Comparison operators that translate to 'greater' and 'less' respectively.

$>=$ / $<=$

Comparison operators that translate to 'greater or equal' or 'less or equal' respectively.

and

A logical operator where both conditions must be true for the whole expression to be true.

or

A logical operator where at least one of the conditions must be true for the whole expression to be true.

$\%$ (Modulus)

An operator used to find the remainder of a division; for example, $65 \% 2$ equals $1$ because $65 \div 2 = 32.5$, leaving a remainder of $1$.

else if

A statement used to evaluate a new condition if the initial $if$ condition was false, as seen in evaluating if a $numero$ is less than $0$.
