Application size is crucial for performance, and optimizing memory usage can significantly reduce an application's memory footprint. This guide explains how to estimate the memory size of Java applications, explore techniques like using primitive types, combining classes, and bit packing for optimizing memory. It also covers using the Java Object Layout (JOL) library for verification and comparing standard Java collections with third-party libraries like Eclipse Collection for additional optimization.
