Blocking Queue

What is a blocking queue in Java?

• Thread-safe data structure
• Non-blocking queue
• Queue with no synchronization
• Queue with fixed size

What are the advantages of using a blocking queue in Java?

• Manual synchronization
• Data race conditions
• Simplified multithreaded communication
• Unordered data flow

How is a blocking queue implemented in Java?

• Synchronization-free
• With semaphores
• Using data structures
• Using locks only

What is the difference between BlockingQueue and BlockingDeque in Java?

• Single-ended vs. double-ended
• Fixed vs. dynamic capacity
• Non-blocking vs. blocking
• FIFO vs. LIFO

What is a blocking queue in multithreading?

• Thread coordination
• Data race conditions
• Non-thread-safe data structure
• Unordered data exchange

Which type of queue is generally better to use in Java, and why?

• Non-blocking for synchronization
• Blocking for coordination
• No preference
• Dynamic size for flexibility

What is the maximum capacity of a Java BlockingQueue?

• Unbounded
• Platform-dependent
• Zero
• Fixed size

What is the difference between a blocking queue and a non-blocking queue?

• Thread safety
• Fixed capacity
• No difference
• Dynamic size

Can you provide an example of how to use the "block" keyword in Java?

• put() and take() methods
• synchronized block
• BlockingQueue class
• No "block" keyword in Java

How is a SynchronousQueue different from a BlockingQueue in Java?

• No differences
