160.Static synchronization

What is static synchronization in Java?

• Synchronizing static variables
• Applying synchronization to static methods or blocks
• Controlling thread execution using static keywords
• Preventing thread interference

Why is static synchronization used in Java?

• To manage thread priorities
• To ensure synchronization across all instances of a class
• To stop thread execution
• To enforce strict ordering of threads

Can we make a static variable synchronized in Java?

• Yes
• No
• Only if it's an integer
• Only if it's declared as volatile

What is static and non-static synchronization in Java?

• Static synchronization is for threads, non-static is for processes
• Static synchronization involves static methods, non-static synchronization involves instance methods
• Static synchronization uses locks, non-static synchronization uses semaphores
• Static synchronization involves multithreading, non-static synchronization involves multiprocessing

What are the two types of synchronization in Java?

• Thread and process synchronization
• Static and dynamic synchronization
• Early and late synchronization
• Static and non-static synchronization

What is the difference between static and non-static synchronization?

• Static synchronization works on class-level, non-static synchronization works on instance-level
• Static synchronization is faster than non-static synchronization
• Static synchronization uses semaphores, non-static synchronization uses locks
• There is no difference

Can we use static variables in multithreading?

• Yes, without any issues
• No, it's not possible
• Only if they are declared as volatile
• Only if they are declared as synchronized

Which is static and synchronized in JDBC?

• ResultSet
• Connection
• Statement
• DriverManager

What are static types in Java?

• Data types that don't change
• Data types declared as static
• Reference types that are non-volatile
• Non-primitive data types

What is the static method in Java?

• A method that can be called on an instance of a class
• A method that can be overridden
• A method that belongs to a class rather than an instance
• A method that is only used in static blocks
