Java Features Quiz

What does 'Simple' mean in the context of Java features?

• Complexity and difficulty in language design

• Simplicity and ease of use in language design

• Elaborate and intricate coding structures

• Advanced and convoluted programming concepts

How does Java ensure 'Robustness' in its programs?

• By allowing unrestricted access to system resources

• Through features like strong type checking, exception handling, memory management, and garbage collection.

• By encouraging memory leaks and inefficient garbage collection

• Through weak type checking and no exception handling

Explain the concept of 'Dynamic' in Java.

• Dynamic in Java allows objects to adapt and change their behavior during program execution.

• Dynamic in Java is a feature that allows objects to be created at compile time

• Dynamic in Java refers to the speed of execution

• Dynamic in Java means objects are static and unchangeable

Why is Java considered 'Secured'?

• Java is not considered 'Secured' because it has many vulnerabilities.

• Java is considered 'Secured' due to its slow performance.

• Java has bytecode verification, classloader, and security manager features.

• Java is not considered 'Secured' because it lacks encryption capabilities.

What does it mean for Java to be 'Platform Independent'?

• Java being 'Platform Independent' means that Java programs can run on any device or operating system that has a Java Virtual Machine (JVM) installed, without needing to be recompiled.

• Java being 'Platform Independent' means it can only run on Apple devices.

• Java being 'Platform Independent' means it can only run on Windows devices.

• Java being 'Platform Independent' means it requires recompilation for each device it runs on.

Describe the 'Object Oriented' nature of Java.

• Java is object-oriented because it uses only objects and no classes

• Java is object-oriented because it does not allow encapsulation

• Java is object-oriented due to its support for classes, objects, inheritance, encapsulation, and polymorphism.

• Java is object-oriented due to its lack of support for inheritance

What does it mean for Java to be 'Architecture-neutral'?

• Java programs can run on any platform with a JVM, making Java architecture-neutral.

• Java is limited to specific hardware architectures

• Java programs can only run on Windows platforms

• Java is not compatible with any other programming languages

How does Java achieve 'Portability'?

• Write Once, Deploy Anywhere principle

• Write Once, Execute Anywhere principle

• Write Once, Run Anywhere principle

• Write Once, Compile Anywhere principle

Why is Java known for its 'High-performance'?

• Java lacks memory management features

• Java has slow execution speed

• Java utilizes a Just-In-Time (JIT) compiler, efficient garbage collection, and platform independence.

• Java is not compatible with multiple platforms

Explain the concept of 'Distributed' in Java.

• Java 'Distributed' concept enables programs to run on multiple networked computers.

• Java 'Distributed' concept allows programs to run on a single computer only.

• Java 'Distributed' concept is not related to networking.

• Java 'Distributed' concept is only applicable to mobile applications.
