Understanding Bytecodes

In the intricate world of the JVM, bytecode serves as the intermediary language that enables Java programs to transcend the boundaries of platform-specific hardware and operating systems. As we delve into the heart of JVM internals, this chapter focuses on deciphering the bytecode, a fundamental component in executing Java applications. Bytecode, represented as a set of instructions, acts as the bridge between high-level Java code and the machine-specific language of the underlying hardware. By comprehending bytecode, developers gain insights into the inner workings of the JVM, empowering them to optimize code performance and troubleshoot intricate issues.

At the core of bytecode lies a diverse set of instructions that dictate the low-level operations performed by the JVM. This chapter unravels the nuances of arithmetic operations, shedding light on how the JVM handles mathematical calculations. From essential addition and subtraction to more complex procedures...
