Boolean

In computer science, the Boolean data type is a data type that has one of two possible values which is intended to represent the two truth values of logic and Boolean algebra. It is named after George Boole, who first defined an algebraic system of logic in the mid 19th century.

boolean isJavaFun = true;
boolean isFishTasty = false;
System.out.println(isJavaFun);     // Outputs true
System.out.println(isFishTasty);   // Outputs false

In computer science, a boolean or bool is a data type with two possible values:
true or false. It is named after the English mathematician and logician George
Boole, whose algebraic and logical systems are used in all modern digital 
computers.

In computer science, the Boolean data type is a data type that has one of two 
possible values (usually denoted true and false) which is intended to represent
the two truth values of logic and Boolean algebra. It is named after George
Boole, who first defined an algebraic system of logic in the mid 19th century.
The Boolean data type is primarily associated with conditional statements, 
which allow different actions by changing control flow depending on whether a 
programmer-specified Boolean condition evaluates to true or false. 
It is a special case of a more general logical data type (see probabilistic 
logic)—logic doesn't always need to be Boolean.
