Multithreaded Programming in Java

What is multithreading in Java?

• A concept of running multiple threads concurrently

• A process of executing multiple tasks simultaneously

• A method to improve application processing

• A way to allocate separate memory for each thread

What are the advantages of Java multithreading?

• It blocks the user during execution

• It allows multiple operations to be performed simultaneously

• It affects other threads if an exception occurs

• It requires more memory allocation

What is the difference between multitasking and multithreading?

• Multitasking is executing multiple tasks, while multithreading is executing multiple threads

• Multitasking requires more memory than multithreading

• Multithreading is a type of multitasking

• There is no difference

What is a thread in Java?

• A lightweight subprocess

• A heavyweight process

• A method of multitasking

• A type of memory allocation

What happens when a thread is in the running state?

• It is waiting for CPU for processing

• It is executing

• It is suspended

• It is terminated

What is the purpose of the Thread class in Java?

• To create and manage threads

• To allocate memory for threads

• To execute multiple processes

• To suspend thread execution

What is the state of a thread when it is created?

• Start

• Run

• Running

• Terminated

What is the difference between process-based and thread-based multitasking?

• Process-based multitasking uses separate memory areas, while thread-based multitasking shares memory

• Thread-based multitasking is more resource-intensive

• There is no difference

• Process-based multitasking is faster

What is the cost of communication between threads?

• High

• Low

• Moderate

• Variable

What is the role of the thread scheduler?

• To manage the execution order of threads

• To allocate memory for threads

• To terminate threads

• To create new threads
