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 · Understanding Java’s data types is fundamental to efficient programming. Each data type has specific use cases and constraints, making it essential to choose the right type for the task at hand.

Even though there are many numeric types in Java, the most used for numbers are int (for whole numbers) and double (for floating point numbers). However, we will describe them all as you continue to read.

Jan 9, 2025 · Numeric data types in Java are divided into two main categories: Integer Data Types and Floating-Point Data Types. Each type serves specific use cases, with varying ranges and precision levels. This article will explore these categories in detail, providing examples and insights to enhance your understanding.

May 24, 2023 · Learn about all eight primitive data types in Java, their memory sizes, default values, and the maximum and minimum values range. 1. Java Primitive Types. 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.

Jan 8, 2024 · In this article, we’ve covered the eight primitive data types supported in Java. These are the building blocks used by most, if not all, Java programs out there, so it’s well worth understanding how they work.

Java Basic Data Types - Learn about the fundamental data types in Java, including int, float, char, and boolean. Understand their roles and how to use them effectively in your programs.

Nov 11, 2010 · BigDecimal is the best when it comes to maintaining accurate floating point calculations, and being able to specify the desired accuracy. I believe float (and to some extent double) offer performance benefits over BigDecimal, but at the cost of accuracy and usability.
