8 Primitive Data Types 1. boolean type. The boolean data type has two possible values, either true or false. Default value: false. They are usually used for true/false conditions. Example 1: Java boolean data type class Main { public static void main(String[] args) { boolean flag = true; System.out.println(flag); // prints true } }

For logical values, Java provides boolean keyword, a primitive data type that holds either true or false as possible values.

Data types are divided into two groups: Primitive data types - includes byte, short, int, long, float, double, boolean and char; Non-primitive data types - such as String, Arrays and Classes (you will learn more about these in a later chapter)

Apr 7, 2025 · Primitive Data Type: These are the basic building blocks that store simple values directly in memory. Examples of primitive data types are boolean, char, byte, short, int, long, float, and double. Note: The Boolean with uppercase B is …

Java Booleans. Very often, in programming, you will need a data type that can only have one of two values, like: YES / NO; ON / OFF; TRUE / FALSE; For this, Java has a boolean data type, which can store true or false values.

Jan 9, 2025 · The Boolean data type in Java is one of the primitive data types that can hold only two possible values: true and false. This binary nature makes it particularly useful for making decisions in code, as it allows for the representation of logical values.

Apr 1, 2025 · Learn what is a Boolean in Java, how to declare & return a Java Boolean, and what are boolean operators along with practical code examples: In this tutorial, we are going to explore boolean in Java which is a primitive data type. This data type has two values i.e. “true” or “false”.

May 24, 2023 · Primitive data types are predefined by the Java Language and named by a reserved keyword. All primitive types can be divided into two groups: boolean types and numeric types. Let’s look at each primitive data type in the below image. The boolean data type has only two valid values: true and false. These two values are called boolean literals.

Jan 28, 2025 · A comprehensive guide on Java's primitive data types, focusing on boolean and char. Learn about their definitions, declarations, usage, and differences with practical examples.

In this article, we will discuss eight primitive types of data: byte, short, int, long, char, float, double, and boolean. The Java programming language is statically-typed, which means that all variables must first be declared before they can be used.
