Note that the class is a design for an Oval object. It itself does no input nor output. class oval private double A, B /semi-major axes publie ovalt covne a doueb l in paraneters // Constructor public oval Cone a colnye daunheb / fill in parameters // fill in code // Setters for A and B public void setA( double newA ) This a hen A /1 fill in code public void setB( double newB ) // fill in code // Getters for A and B public double getAC) /1 fi1l in code public double getB

Explanation / Answer

TestOval.java

//Area of an Oval is 3.14*A*B
class Oval {

private double A, B;//semiAxix of an Oval

public double getA() {
return A;
}

public Oval(double A, double B) {
this.A = A;
this.B = B;//Constructor Oval with two Arguments
}
//setter and getter methods
public void setA(double A) {
this.A = A;//setting value
}

public double getB() {
return B;//getting values
}

public void setB(double B) {
this.B = B;
}

public String toString() {
String str = "Area of an Oval :";
System.out.println(str);
return str;
}

public double Area() {
double area = 3.14 * A * B;
System.out.println(area);
return area;
}
}

public class TestOval {

public static void main(String args[]) {//main method
Oval ovalX = new Oval(3.2, 3.4);//creating object and passing values
ovalX.toString();//calling toString method
ovalX.setA(9.23);

ovalX.Area();//callingArea method
}
}

output

Area of an Oval :
98.53948000000001
