Java Full Stack Part-4 - Data Type смотреть онлайн

It appears you're looking for a description of different data types. Data types are classifications of data items, indicating the kind of value they can hold and the operations that can be performed on them. Here's a brief description of data types:

Integer (int): Represents whole numbers, both positive and negative, without decimal points. For example, 42 or -17.

Float (float): Stores numbers with decimal points, allowing for fractional values. For example, 3.14 or -0.5.

String (str): Holds sequences of characters, such as text, letters, and symbols. For example, "Hello, World!" or "12345".

Boolean (bool): Represents binary values - True or False, often used for logical comparisons and conditions.

List: A collection of values that can be of various data types, ordered and indexed. For example, [1, 2, 3, "apple", "banana"].

Tuple: Similar to a list, but immutable (cannot be changed after creation). Often used for fixed sequences of elements.

Dictionary: Stores key-value pairs, allowing you to access values by their corresponding keys. For example, {"name": "John", "age": 30}.

Set: Represents an unordered collection of unique elements, often used for mathematical operations like union and intersection.

Array: Used in some programming languages to store collections of elements of the same data type, often for numerical data.

Object: In object-oriented programming, objects encapsulate both data (attributes) and the methods (functions) that operate on the data.
