Boolean Types

Frequently in programming, you encounter scenarios where a data type is required to hold only one of two values, such as:

YES / NO
ON / OFF
TRUE / FALSE

Java provides a boolean data type precisely for this purpose, capable of accepting only the values true or false.

Example

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

Boolean values predominantly serve in conditional testing, with further exploration into booleans and conditions awaiting in subsequent sections of this tutorial.
