Why byte is -128 to 127 | The Foundational Lesson for short, int, and long 💡

Have you ever wondered why an 8-bit signed integer in Java has a range of -128 to 127? In this deep dive, we break down the logic behind the integer data type ranges, using the humble `byte` to explain the concept. Specifically, you'll learn: How signed integers (using two's complement) are represented. The exact arithmetic behind the -128 to 127 range. Why the range is determined by the bit width and whether the number is signed or unsigned. Understanding this concept is crucial for any Java programmer. Watch now to demystify data type ranges for all Java's primitive integers! What other core computer science concepts would you like me to demystify? Let me know in the comments!
