Java - Calculator Class

Build a class called Calculator that emulates basic functions of a calculator: add, subtract, multiply, divide, and clear. The class has one
private member field, double value, for the calculator's current value. Implement the following Constructor and instance methods as listed
below:
}
• public Calculator() - Constructor method to set the member field to 0.0
• public void add(double val) - add the parameter to the member field
• public void subtract(double val) - subtract the parameter from the member field
• public void multiply(double val) - multiply the member field by the parameter
public void divide (double val) - divide the member field by the parameter
• public void clear() - set the member field to 0.0
• public double getValue() - return the member field
Given two double input values num1 and num2, the program outputs the following values:
1. The initial value of the instance field, value
2. The value after adding num1
3. The value after multiplying by 3
4. The value after subtracting num2
5. The value after dividing by 2
6. The value after calling the clear() method
Ex: If the input is:
10.0 5.0
the output is:
0.0
10.0
30.0
25.0
12.5
0.0
import java.util.Scanner;
public class calculator {
// TODO: Build calculator class with methods and fields Listed above
/* Type your code here. */
public static void main(String[] args) {
calculator calc = new Calculator();
}
Scanner keyboard = new Scanner(System.in);
double num1 keyboard.nextDouble();
double num2 = keyboard.nextDouble();
// 1. The initial value
System.out.println(calc.getvalue());
// 2. The value after adding num1
calc.add(num1);
System.out.println(calc.getvalue());
// 3. The value after multiplying by 3
calc.multiply(3);
System.out.println(calc.getvalue());
// 4. The value after subtracting num2
calc.subtract (num2);
System.out.println(calc.getvalue());
// 5. The value after dividing by 2
calc.divide (2);
system.out.println(calc.getvalue());
// 6. The value after calling the clear() method
calc.clear();
System.out.println(calc.getvalue());
