Boolean Logic & Conditional Statements

Null

True

Error

False

It removes the necessity to write constructors for objects.

It automatically parallelizes the code for faster execution on multi-core processors.

It separates concerns by grouping related variables and behaviors together.

It reduces memory usage by sharing methods among different classes.

(a > 0 && b > 0)

$((a + b) < 0)$

$((a + b) > 0)$

$(a > 0) || (b = -0)$

!(p || q) && r

(!p && !q) || r

$!p || !q || r$

!(p && q) || r

To improve code performance

To simplify code logic

To evaluate multiple conditions within an if statement

To combine multiple if statements into one

num ≤ threshold but flag’s value isn’t known

flag is false and num ≤ threshold

The statement always returns true

flag’s value isn’t known but num > threshold

$( (score >= 90) || (score < 100) )$

( (score => 90) && (score =! 100) )

$( (score > 90) || (score <= 10) )$

( (score >= 90) && (score <= 100) )

str.length()%2==0 || str.charAt(6)!=str.charAt(7)

(str.length()<7) && !(str.charAt(6)==str.charAt(7))

str.length()>7 && str.charAt(6)!=str.charAt(7)

str.length()%2==0 && str.charAt(6)==str.charAt(7)

(alpha \geq 0) && (beta \geq 0)

$((alpha < zero) || (beta - zero))$

$(alpha = .beta)$

$((alphabeta) < zero)$

Saving storage space by allowing one method name to reference multiple implementations at once.

Providing two methods with the same name but different parameters to perform similar tasks efficiently.

Giving each method a unique name based on its functionality to avoid confusion during calling procedures.

Increasing processing speed by loading methods into memory only when they are called.
