Java Boolean Data Types: Understanding True and False Values

Explore Java's boolean data type, which is essential for representing values that can only be true or false. This guide delves into the significance of boolean types in programming and their applications in control flow, conditional statements, and logical operations. Learn how to effectively utilize boolean data types to enhance decision-making capabilities in your Java applications.

Boolean Types

In programming, you often need a data type that can only have one of two values, such as:

  • YES / NO
  • ON / OFF
  • TRUE / FALSE

For this purpose, Java provides a boolean data type, which can only be either true or false:

Example

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