What is bytecode in the context of Java applications?
Bytecode is the format to which Java applications are typically compiled and can run on any Java virtual machine (JVM) regardless of the underlying computer architecture.
How does the syntax of Java compare to C and C++?
The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them.
What dynamic capabilities does the Java runtime provide?
