A(n) _____ exists when there are functional dependencies such that XY is functionally dependent on WZ, X is functionally depende
Nat2105 [25]

A partial dependency exists.

We have two types of dependency. The partial dependency and the transitive dependency.

The answer here is partial dependency. It occurs when the attribute only depends on some parts of the element. In such attribute, the primary key is the determinant.

It can be shown as;

XY→WZ , X→W and XY is the primary key or the only candidate key

Which of the following would be a valid method call for the following method? public static void showProduct (int num1, double n
Alenkinab [10]

Answer:

showProduct(int,double)

for example: showProduct(10,10.5) is the correct answer even showProduct(10,10.0) is also correct but showProduct(10.0,10.5) or showProduct(10,10) or showProduct(10.0,10) are wrong calls.

Explanation:

The code is

  1.       <em>public static void showProduct (int num1, double num2){</em>
  2. <em>       int product;</em>
  3. <em>       product = num1*(int)num2;</em>
  4. <em>       System.out.println("The product is "+product);</em>
  5. <em>       }</em>

showProduct is function which asks for two arguments whenever it is called, first one is integer and second one is of type double which is nothing but decimal point numbers. Generally, in programming languages, 10 is treated as integer but 10.0 is treated as decimal point number, but in real life they are same.

If showProduct( 10,10.0) is called the output will be 'The product is 100'.

Strange fact is that, if you enter showProduct(10,10.5) the output will remain same as 'The product is 100'. This happens because in the 3rd line of code,which is <em>product=num1*(int)num2</em>, (int) is placed before num2 which makes num2 as of type integer, which means whatever the value of num2 two is given, numbers after decimal is erased and only the integer part is used there.

This is necessary in JAVA and many other programming languages as you <u>cannot</u><u> multiply two different datatypes</u> (here one is int and another is double). Either both of them should be of type int or both should be of type double.
