What are the different types of data types available in Java?

Java is a strongly typed programming language that requires all variables to be declared before they can be used. The type of a variable determines the range of values it can hold and the operations that can be performed on it.

Java supports two categories of data types:

• Primitive data types: These are the basic data types provided by Java, including boolean, byte, char, short, int, long, float, and double.
• Reference data types: These are more complex data types that are used to refer to objects, such as arrays, classes, and interfaces.

Primitive data types are further classified into four groups:

• Boolean: The boolean data type represents one bit of information and can have two possible values: true and false.
• Numeric: The numeric data types represent numbers and can be further divided into integer and floating-point types.
• Character: The char data type is a single 16-bit Unicode character.
• Integral: The integral data types include byte, short, int, and long, and represent whole numbers with varying ranges of values.

Java's data type system provides a powerful set of tools for developers to work with. By choosing the appropriate data type for a variable or object, Java programmers can ensure that their programs are efficient, reliable, and easy to maintain.
