Java Programming L2 Quiz

What is the intermediate language into which Java instructions are translated before execution?

• Assembly

• Machine Code

• Bytecode

• High-level Code

What is the primary function of a compiler?

• To translate a program written in a high-level language into an equivalent machine language

• To interpret and run a program line-by-line

• To provide an interface for user interaction with the program

• To execute a program written in a high-level language

Which of the following statements is NOT true about the Java Virtual Machine (JVM)?

• The JVM is software that interprets Java bytecode.

• Java programs are executed within the JVM.

• The JVM is a physical machine.

• The JVM translates Java bytecode into object code at runtime.

Why is Java considered simpler and easier to learn compared to C++?

• Java supports pointers and operator overloading like C++.

• Java has a more complex syntax than C++.

• Java has left out or re-implemented confusing concepts from C++.

• Java includes all features of C++ without any changes.

What does it mean when we say that Java is object-oriented?

• Everything in Java is treated as a function.

• Everything in Java is considered an object with data and behavior.

• Java does not support the use of objects.

• Java cannot be extended because it lacks an object model.

How does Java ensure robustness in its programming environment?

• Java eliminates all errors during runtime.

• Java focuses only on compile-time error checking.

• Java improves memory management with automatic garbage collection and handles errors using exception handling.

• Java removes the need for exception handling altogether.

What makes Java a platform-independent language?

• Java programs are compiled directly into machine code specific to each platform.

• Java programs are compiled into bytecode, which can be run on any machine with the Java Runtime Environment (JRE).

• Java programs must be recompiled for each different platform.

• Java programs can only run on Windows operating systems.

Why is Java considered a secure programming language?

• Java programs interact directly with the operating system, making them highly secure.

• Java has built-in security features that help prevent viruses and tampering.

• Java programs cannot be run in the Java Runtime Environment (JRE).

• Java does not prioritize security in its design.

What is a key benefit of Java's multithreading feature?

• It allows multiple programs to run on different machines simultaneously.

• It enables programs to perform multiple tasks at the same time by sharing the same memory and resources.

• It prevents programs from running multiple threads.

• It requires each thread to use its own memory and resources, reducing efficiency.

Why is Java considered architecturally neutral?

• Java bytecodes are generated for specific computer architectures.

• Java bytecodes can be interpreted on any machine, regardless of the computer architecture.

• Java programs must be recompiled for each different computer architecture.

• Java is limited to running only on certain types of machines.
