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)

This tutorial covers various aspects of the Java float data type, including: The type of values a float can store and its precision. How to declare, initialize, and update a float variable. Maximum and minimum values a float data type can represent. Printing a float value to the console output. Performing arithmetic operations on floating-point ...

Apr 7, 2025 · Java has two categories in which data types are segregated. 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 a wrapper class for the primitive boolean type.

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.

Sep 3, 2022 · The float data type stores a decimal value with a precision of 6–7 digits. 12.12345, for example, is a float that can be kept, whereas 12.123456789 is not. When expressing a float data...

Apr 9, 2025 · Java has two main categories: primitive and non-primitive types. Primitive types include `int`, `char`, `float`, and `boolean`, which store simple values directly. Non-primitive types, like arrays and objects, store memory addresses pointing to the data.

Jan 28, 2025 · Understand the differences between Java's primitive data types float and double. Learn about memory consumption, precision, and use cases to optimize your Java applications.

Java uses data types to define the type of data a variable can hold. There are two main categories of data types: primitive and non-primitive. Primitive data types include: byte, short, int, long, float, double, boolean, and char.

Java has a Float class, which defines three constants that represent positive infinity, negative infinity, and NaN of the float data type. The following table lists these three float constants and their meanings.

Float Data Type. A float is a decimal number, like 3.14, -0.001, 2.71828, etc. This is how a value 3.14, of data type float, is assigned to a variable pi: pi = 3.14 ... In Java, the null keyword can only be assigned to non-primitive data type variables, like strings or arrays. C++ does not have a direct equivalent to null, ...
