Программирование: Java. Типы данных

The data type is determined by three components:

• a set of values ​​or objects;
• a set of operations that can be applied to all values ​​in a set;
• presentation of data determining their storage.

What are the data types in Java?

The programming language contains some predefined built-in types and allows programmers to define their own custom ones.

In Java, data types are divided into primitive and referential.

“Primitive” means that its further division is impossible. To expand or change its programming language does not allow. This data type is described by primitive and other user types.

A variable of primitive type contains a value, and a reference one contains the address of the object in memory.

Java language. Data Types: Time and Date

Compound data is divided into classes, interfaces, and arrays. The members of the interface type are abstract methods and constants. In Java, date and time data types are specified by the Date () constructor:

• d = new Date ().
