Java bytecode is an intermediate code generated by the Java compiler after the compilation of source code. It is essentially the machine-level code that runs on the Java Virtual Machine (JVM) . Whenever a class is loaded, it gets a stream of bytecode per class method, and whenever that method is called during the execution of a program, the bytecode for that method gets invoked. The bytecode is the common piece between the compiler (which creates it) and the interpreter (which runs it) .
Bytecode is generated when the Java compiler converts the source code or the Java program into the bytecode (or machine code) . The bytecode is present in a .class file and is equivalent to the assembler in C++ . With the help of Java bytecode, we achieve platform independence in Java. The JVM is stack-based, so it uses a stack implementation to read the codes.
Bytecode is a set of instructions for the JVM that is responsible for interpreting them. It is a non-runnable code that requires or relies on an interpreter, which is the JVM. The JVM is responsible for allocating the required resources to run the bytecode. Bytecodes are non-runnable codes that rely on the availability of an interpreter, and the JVM is a machine-level language code that runs on the JVM.
In summary, Java bytecode is an intermediate code generated by the Java compiler after the compilation of source code. It is essentially the machine-level code that runs on the JVM and is responsible for interpreting the set of instructions. The bytecode is generated when the Java compiler converts the source code or the Java program into the bytecode (or machine code). The bytecode is present in a .class file and is equivalent to the assembler in C++. The JVM is responsible for allocating the required resources to run the bytecode, and it is a machine-level language code that runs on the JVM.
