Description: The ‘Long’ data type in Java is a primitive type that represents a signed 64-bit integer. This means it can store integer values over a much wider range than the ‘int’ type, which only uses 32 bits. The range of values it can handle goes from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. This capability makes it an ideal choice for applications that require handling large numbers, such as financial calculations or counting items in large datasets. Additionally, ‘Long’ is part of Java’s standard library, meaning it is available in all versions of the language and can be used in any Java application. Like other primitive types, ‘Long’ has efficient performance in terms of memory and processing speed, making it suitable for high-performance applications. In Java, it can be used both as a primitive type and in its object form through the ‘Long’ class, which provides useful methods for manipulating long numbers, such as converting strings to numbers and vice versa.
