Create a CalculatorTest class that contains the main method. 1. Get two double numbers as input and create an object of the ScientificCalculator Class with those two numbers. 2. Then call the 8 operations one by one sequentially and display the result. Code must be written in Java.

(Sample input/output: Enter number 1: 2 Enter number 2: 3 Add() result is : 5 Sub() result is: -1 . Power() result is: 8 sqrtNum1 result is:)

The Problem:

Given the following class diagram (see Chapter 3 Slide 34 and 36

if you are not familiar

with the diagram).

The diagram is

self

-explanatory

. Remember

means private and

+ means public

in the diagram

.

Conver

t the class diagram into a java code. You can easily see the class name, variables and methods from

the diagram.

The diagram says that

Scientific

Calculator

class

inherits

the

Calculator

class. In many operations in the

scientific calculator class

, you can utilize the

java.Math class

s methods

(https://docs.oracle.com/javase/8/docs/api/java/lang/Math.html

).

Calculator

-

num1: double

-

num2: double

<>Calculator(

num1: double, num2:double)

+set

Num1(num1: double)

+setNum2(num2: double)

+getNum1(): double

+getNum2(): double

+add(): double

+sub(): double

//num1

-num2

+mul(): double

+div(): double

//num1/num2

Create a CalculatorTest class that contains the main method.

1.

Get two double numbers as input and create an object of the Scientific

Calculator Class

with

those two numbers.

2.

The

n call

the

8 operations one by one sequentially

and display the result.

ScientificCalculator

<>Calculator(num1:

double, num2:double)

//dont forget to call

the super classs constructor from here

. Otherwise it willshow error as we dont have a

constructor without any parameter.

+power(): double //returns num1 ^ num2

+reminder(): int

//returns the reminder of num1/num2 as integer. So,

convert num1 and num2 to int before performing the operation

+sinNum1(): double

//r

eturns the trigonometric sine of num1.

+sqrtNum1(): double

//returns the square root o

f Num1

Sample input/output:

Enter number 1: 2

Enter number 2: 3

Add() result is : 5

Sub() result is: -

1

.......

Power()

result is: 8

......

sqrtNum1 result is:

The code structure should look like the following

. Note

that

all the classes ar

e written in a single file.

So, in eclipse you can just create one class and write everything in the same file

:

File name: CalculatorTest.java

//all the require import statements

class Caclulator {

class body

}

Class .....{

Class body

}

Public class CalculatorTest{

Class body.

}
