Multiple Choice

Which language is designed to run on the Java Virtual Machine and is widely used for cross-platform applications?

Java enables cross-platform applications because it runs on the Java Virtual Machine, which abstracts away differences between operating systems and hardware. When you compile Java source, it becomes bytecode that the JVM can execute on any device with a compatible JVM, letting the same program run everywhere without modification. This "write once, run anywhere" capability is why Java became so widely used for cross-platform development—the language and its runtime are designed around that portability and the safety and performance features the JVM provides. Pseudocode isn’t an actual runnable language; it’s a human-friendly outline, so it isn’t something the JVM executes. Machine language is specific to a particular CPU architecture, so code written for one type of processor won’t run on another without rewriting or recompiling. Pascal is an older language with its own history of compilers, but it’s not designed around the JVM, and it isn’t the language most associated with cross-platform development via the JVM.
