Quick Summary

Java Bytecode is an intermediate language used in the Java programming language. Instead of compiling directly into machine code for a specific computer, Java code is translated into Bytecode. This Bytecode is then interpreted by the Java Virtual Machine (JVM), which acts as a virtual computer. This process allows Java programs to run on various platforms, embodying the "write once, run anywhere" principle, making it ideal for web-based and distributed applications.12
