Que. 1 Consider the following code snippet.
class MyThread extends Thread {
public void run() {
for (int i = 0; i < 3; i++) {
System.out.println("Running thread: " + i);
}
}
}
public class Main {
public static void main(String[] args) {
MyThread thread = new MyThread();
thread.run();
System.out.println("Main method complete.");
}
}
What will be the output of the program?
a) Running thread: 0
Running thread: 1
Running thread: 2
Main method complete.
b) Running thread: 0
Main method complete.
Running thread: 1
Running thread: 2
c) Main method complete.
d) Error: The thread was not started using start()
.

Que. 2 Which of the following best describes the concept of multithreading in Java?
a) Multiple threads execute concurrently, sharing the same memory space.
b) Only one thread executes at a time, ensuring sequential execution.
c) Threads in Java cannot communicate with each other.
d) Threads require separate memory allocation for each thread to run.

Que. 3 What will happen when the following code is executed?
class ExampleThread extends Thread {
public void run() {
System.out.println("Thread is running.");
}
}
public class Main {
public static void main(String[] args) {
ExampleThread thread = new ExampleThread();
thread.start();
thread.start();
}
}
a) The program will execute successfully, printing "Thread is running."
twice.
b) The program will throw an error when attempting to start the thread a second time.
c) The program will terminate without any output.
d) The thread will run only once, and the second start()
call will be ignored.

Que. 4 Find the error in the following program:
class RunnableExample implements Runnable {
public void run() {
for (int i = 1; i <= 3; i++) {
System.out.println("Runnable thread: " + i);
}
}
}
public class Main {
public static void main(String[] args) {
RunnableExample runnable = new RunnableExample();
runnable.run();
System.out.println("Main method ends.");
}
}
a) The program will throw an error because Runnable
cannot be executed directly.
b) The program will run successfully but will not create a new thread.
c) The program will create a new thread and execute concurrently.
d) The program will throw a runtime error because Thread
is not used.

Que. 5 What will happen when the following code is executed?
class RunnableExample implements Runnable {
public void run() {
for (int i = 1; i <= 3; i++) {
System.out.println("Thread running: " + i);
}
}
}
public class Main {
public static void main(String[] args) {
RunnableExample task = new RunnableExample();
Thread thread = new Thread(task);
thread.start();
}
}
a) The program will throw a compile-time error because Runnable
is not a thread.
b) The program will execute successfully, and the run()
method will run in a new thread.
c) The program will execute the run()
method directly on the main thread.
d) The program will throw a runtime error because Runnable
is not properly implemented.

Que. 8 Consider the following program:
class PriorityExample extends Thread {
public void run() {
System.out.println(Thread.currentThread().getName() +
" with priority " +
Thread.currentThread().getPriority());
}
}
public class Main {
public static void main(String[] args) {
PriorityExample t1 = new PriorityExample();
PriorityExample t2 = new PriorityExample();
t1.setPriority(Thread.MIN_PRIORITY);
t2.setPriority(Thread.MAX_PRIORITY);
t1.start();
t2.start();
}
}
Which of the following is true about the output?
a) The thread with the higher priority is guaranteed to execute first.
b) The thread with the lower priority will never execute.
c) The order of execution depends on the JVM and OS scheduling policies.
