thread

What is multithreaded programming?

• It’s a process in which two different processes run simultaneously

• It’s a process in which two or more parts of same process run simultaneously

• Its a process in which many different process are able to access same information

• Its a process in which a single process can access information from many sources

Which of these statements is incorrect?

• By multithreading CPU’s idle time is minimized, and we can take maximum use of it

• By multitasking CPU’s idle time is minimized, and we can take maximum use of it

• Two thread in Java can have same priority

• A thread can exist only in two states, running and blocked

Which of this class is used to make a thread?

• String

• System

• Thread

• Runnable

Which of this interface is implemented by Thread class?

• Runnable

• Connections

• Set

• MapConnections

Which of this method of Thread class is used to suspend a thread for a period of time?

• sleep()

• terminate()

• suspend()

• stop()

Which of this method is used to begin the execution of a thread?

• run()

• start()

• runThread()

• startThread()

Complete the program code below that is suitable to start a thread.

class X implements Runnable

{

public static void main(String args[])

{

/* Missing code? */

}

public void run() {}

}

• Thread t = new Thread(X);

• X x1 = new X();

  Thread t = new Thread(x1);

  t.start();

• Thread t = new Thread(X);

  t.start();

• Thread t = new Thread();

  x.run();

Select method that must be defined by a class implementing the java.lang.Runnable interface.

• public void runs()

• public void run()

• public void start()

• void run(int priority)

What will be the output of the following program code?



• The program does not compile because the start() method is not defined in the Test class.

• The program compiles, but it does not run because the start() method is not defined.

• The program compiles, but it does not run because the run() method is not implemented

• The program compiles and runs fine
