Boolean data type indicates true or false values. For usability reasons, Booleans values are sometimes shown as Yes or No.
Instead, expressions in the Java programming language that operate on boolean values are compiled to use values of the Java virtual machine int data type. Where Java programming language boolean values are mapped by compilers to values of Java virtual machine type int, the compilers must use the ...
Type Conversions When Visual Basic converts numeric data type values to Boolean, 0 becomes False and all other values become True. When Visual Basic converts Boolean values to numeric types, False becomes 0 and True becomes -1. When you convert between Boolean values and numeric data types, ...
A Boolean value represents a truth value; that is, TRUE or FALSE. A Boolean expression or predicate can result in a value of unknown, which is represented by the null value. The following data types can be cast to the BOOLEAN data type: CHAR or VARCHAR can be cast to a BOOLEAN value...
boolean: The boolean data type has only two possible values: true and false. Use this data type for simple flags that track true/false conditions. This data type represents one bit of information, but its "size" isn't something that's precisely defined. ...

A Boolean value represents a truth value of TRUE or FALSE. A Boolean expression or predicate can result in a value of unknown, which is represented as the null value. The BOOLEAN type is a built-in data type that can only be used as the data type of: ...
Using Boolean Values See Also Whereas numeric and string data types can have a virtually unlimited number of different values, thebooleandata type can have only two. They are the literalstrueandfalse. A Boolean value expresses the validity of a condition (tells whether the condition is true or...

Boolean values There is a duality built in our world. There is a Heaven and Earth, water and fire, jing and jang, man and woman, love and hatred. In Java thebooleandata type is a primitive data type having one of two values:trueorfalse. ...
