The code for the question is -

Code: Select all

class MyClass implements Runnable
{
	int n = 0;
	public MyClass(int n){ this.n = n; }
	public static void main(String[] args)
	{
		new MyClass(2).run();
		new MyClass(1).run();
	}
	public void run()
	{
		for(int i=0; i<n; i++)
		{
			System.out.println("Hello World");
		}
	}
}

For the output I chose the answer that "1 new thread is created by the program". Is that not so given that the main() thread is created?

[admin]

The main thread is created by the JVM. The given code does not create any thread.

It will print "Hello World" twice. - It will print "Hello World" thrice.

I thought so, but since it didn't say "exactly twice" it is still true!

[admin]

The option has now been modified to include the word "exactly" to avoid this confusion.

thank you for your feedback!
