Java long

Java **long** is a primitive data type used to represent signed 64-bit integers. It has a wider range of values compared to the **int** data type, allowing it to store larger whole numbers. The range of **long** values is approximately -9.2 quintillion to 9.2 quintillion. **long** values are commonly used for storing large integers, such as timestamps, file sizes, and numerical identifiers. In Java, **long** literals are suffixed with an "L" (e.g., 123L). **long** data type is also used in scenarios where precision and range are critical, such as scientific calculations and financial applications. Understanding how to work with **long** effectively is essential for handling large integer values accurately and efficiently in Java programs.
