Research Guides: Boolean Operators: A Cheat Sheet: Home
Boolean logic (named after mathematician George Boole) is a system of logic to designed to yield optimal search results. The Boolean operators, AND, OR, and NOT, help you construct a logical search. The circle diagrams that help illustrate the relationships between the sets used in Boolean logic were named after another mathematician, John Venn.

Boolean logical operators - AND, OR, NOT, XOR
Binary & (logical AND), | (logical OR), and ^ (logical exclusive OR) operators. Those operators always evaluate both operands. Binary && (conditional logical AND) and || (conditional logical OR) operators. Those operators evaluate the right-hand operand only if it's necessary.

Logical Operators in Programming - GeeksforGeeks
Logical operators manipulate boolean values (true or false) and return a boolean result based on the logical relationship between the operands. They are used to combine or modify boolean (true/false) values and are used in decision-making processes in programming.

Java Booleans - W3Schools
In the examples below, we use the equal to (==) operator to evaluate an expression: Let's think of a "real life example" where we need to find out if a person is old enough to vote. In the example below, we use the >= comparison operator to find out if the age (25) is greater than OR equal to the voting age limit, which is set to 18: Cool, right?

Basics of Boolean Algebra: Its Operators, Laws, and Examples
We will discuss the three most common Boolean operators, which are given below: A proposition is a declarative statement that may be true or false but cannot be both simultaneously. If p is any proposition, its negation is denoted by ¬p, read “not p”.

What Boolean Logic Is & How It’s Used In Programming - Codecademy
Boolean logic is a type of algebra in which results are calculated as either TRUE or FALSE (known as truth values or truth variables). Instead of using arithmetic operators like addition, subtraction, and multiplication, Boolean logic utilizes three basic logical operators: AND, OR, and NOT.
