(TCOs 1, 2, and 6) What error, if any, is in the following code?
public class Test
{
         private int num;
         public void getNum( )
         {
                  return num;
         }
}

Explanation / Answer

1. Option c: An object named Automobile is created.

Reason: Automobile car = new Automobile(); This java syntax indicates that there is a class called Automobile. We are creating an object of that class, named car. So the fact that the object is named Automobile is false. Automobile is the class and object name is car.

2. Option b: main

Reason: The main function is automatically called when you run the java code. For all other functions, you have to explicitly write the name of the function in the line where you want to call it.

3. Option a: %f

Reason: This is how the function specific was designed.

4. Option c: getNum must return int, not void

Reason: getNum function returns num, which is of type int. So the return type of the function should be the same as the element which is being returned. Hence here void is incorrect, it should be int instead of void.
