Description: IntegerCache is a feature of Java that allows for the reuse of Integer object instances for values ranging from -128 to 127. This implementation is based on the idea that integer numbers in this range are commonly used in programming applications, and their repeated creation and destruction can be costly in terms of performance. By caching these objects, Java avoids creating new instances every time an Integer within this range is needed, reducing the load on the garbage collector and improving memory efficiency. This optimization is particularly useful in operations involving comparisons and calculations with integers, as it allows reused instances to be compared by reference rather than by value, resulting in faster performance. IntegerCache is an example of how Java implements optimization techniques to enhance object handling efficiency, and it is an integral part of the data type system in the language, ensuring that operations with integers are both fast and efficient.
