Answer:
A traditional database has a static memory space, and at times this can be more than what you need, and this happens almost always. However, in the case of a cloud database, you are allowed to choose the DB space that you feel will be used, and you can scale it up and down anytime according to the demand. Suppose more user is using your software, you can scale up the database, or else you can scale down. And you are going to pay for what DB space you used, and for how long. And that is why the cloud database cost is less than a traditional database.

Answer:
b. When an array is created, the number of elements must be placed in square brackets following the type of element being stored.
Explanation:
In Java an uninitialized array contains null values. Thus statement c is true as well.
Also generally for initializing and displaying array elements a for loop is used. Hence statement d is also correct.
In Java syntax for declaring an array is as follows:
Array declaration:
type [] array_name ;
Array instantiation(memory allocation):
type [] array_name = new array_name [size of array];
From the above it can be seen that the statement a is true and statement b is false as number of elements in array are not mentioned after the type.
Hence the correct answer is b.
