In this video, we dive deep into one of the most important internal concepts of Java, how numbers are actually stored in memory. This is a step-by-step conceptual lecture where we understand: • How negative numbers are stored using 2’s Complement • Step-by-step conversion process • Why 2’s complement is used internally • Floating point number storage explained • Exponent representation and normalization • What is Bias in floating point representation • Normal vs Edge cases in floating point numbers • Why exact values are sometimes NOT retrieved • Precision errors explained simply This lecture is extremely important for: Java beginners who want strong fundamentals Placement preparation Interview understanding Computer memory & number representation concepts Writing better and bug-free code By the end of this video, you will understand how Java internally stores numbers and why certain floating point values behave unexpectedly. This video is part of the Java Full Course 2026 playlist — follow the lectures in order for best understanding. Why Learn Java? Java is one of the most powerful and widely used programming languages in the world. It is used in: Backend development Enterprise applications Android development Banking systems Large-scale distributed systems If you want to master Data Structures, Spring Boot, Microservices, or System Design, Java fundamentals are essential.
