WebBytecode in Java is a set of instructions for the Java Virtual Machine. Bytecode is a platform-independent code. Bytecode is a code that lies between low-level language and high-level language. After the Java code is compiled, the bytecode gets generated, which can be executed on any machine using JVM. Bytecode is the intermediate representation of a Java program, allowing a JVM to translate a program into machine-level assembly instructions.

"WebJava bytecode obfuscates the original structure of a Java expression in the source code. So a simple expression such as (c1 c2) or (c1 && c2) may be captured in the bytecode in 4 different ways (as shown in the paper). And correspondingly, when we reconvert the bytecode back into Java source code, there are four different ways this may happen. " - Bytecodes in java
