Solution

The output of the program will be 2.0.

Here's the step by step explanation:

  1. The program defines a class named Num with a constructor that takes a double as an argument. This constructor prints out the value of the argument.

  2. The Test class extends the Num class.

  3. In the main method of the Test class, an instance of the Num class is created with the argument 2.

  4. This calls the constructor of the Num class, which prints out the value 2.0 (since it's a double).

So, the output of the program is 2.0.
