Boxing and Streams in Java

In today's world, various levels of abstraction exist, similar to the multiple levels in Java architecture. One important concept in Java is Boxing, which is not about physical boxes but rather a method to manage memory and objects efficiently. To understand Boxing, one must first grasp two core techniques in Java: Primitive Data Types and Wrapper Classes. Primitive Data Types include int, float, and double, while Wrapper Classes are Object Templates that convert these primitive types into corresponding Objects, such as Integer and Float. For example, Integer wraps int and Character wraps char. Boxing involves converting a primitive data type into its corresponding wrapper class, a process known as Autoboxing. This technique optimizes performance by handling memory and objects effectively.
