How should you write methods in the ElectricAccount class at line n1 so that the member variable bill is always equal to the value of the member variable kwh multiplied by the member variable rate?

Any amount of electricity used by a customer (represented by an instance of the customer class) must contribute to the customer#39;s bill (represented by the member variable bill) through the method useElectricity method. An instance of the customer class should never be able to tamper with or decrease the value of the member variable bill.

Which of the following data types will allow the following code snippet to compile?

Ensurepass 2018 PDF and VCE

  1. long

  2. double

  3. int

  4. float

  5. byte

Answer: B,D Explanation:

Option B and D are the correct answer.

Since the variables I and j are floats, resultant will be float type too. So we have to use float or primitive type which can hold float, such a primitive type is double, it has wider range and also can hold floating point numbers, hence we can use double or float for the blank.

As explained above options B and D are correct.

long and int can#39;t be used with floating point numbers so option A is incorrect.

Option E is incorrect as it have smaller range and also can#39;t be used with floating point numbers.

Question No: 68

Given:

Ensurepass 2018 PDF and VCE

What is the output?

A. 2015-03-27

B. 2015-04-27

C. 2015-02-27

  1. Compilation fails due to error at line 6.

  2. Compilation fails due to error at line 8.

Answer: A Explanation:

To create we have used following method with LocalDate class; public static LocalDate of(intyear, int month, int dayOfMonth)

Here we need to remember that month is not zero based so if you pass 1 for month, then month will be January.

Then we have used period object of 1 day and add to date object which makes current date to next day, so final output is 2015-03-27. Hence option A is correct. https://docs.oracle.com/javase/tutorial/datetime/iso/datetime.html

Question No: 69

Given:

Ensurepass 2018 PDF and VCE

Which of the following is equivalent to the above code fragment?

A. System.out.printLn(xgt;10?quot;gt;,#39;: quot;lt;quot;:,#39;=quot;);

B. System.out.println(xgt;10? quot;gt;quot;?quot;lt;quot;:quot;=quot;);

C. System.out.println(xgt;10?quot;gt;quot;:xlt;10?quot;lt;quot;:quot;=quot;);

D. System.out.printLn(xgt;10?quot;gt;quot;?,#39;lt;quot;?quot;=quot;);

E. None of the above

Answer: B Explanation:

Option A is incorrect as we can#39;t use abstract with non abstract method, (here method has method body.)

Option C is incorrect as when overriding method we can#39;t use more restrictive access modifier, so trying to use private to override default access Level method causes a compile time error.

Option D is incorrect as default methods (not methods with default access level) are allowed only in interfaces.

Option E is incorrect as method all ready has void as return type, so we can#39;t add int there. Option B is correct as we can use final there, since the method is non abstract https://docs.oracle.com/javase/tutorial/java/landl/polymorphism.html
