This is a JAVA question

This is a main class & method

These are the two sub classes

Main Class: 4 errors

SuperClass Circle: 3 errors

SubClass Oval: 2 errors

What are they and how can they be fixed?

Explanation / Answer

In Midweek_Week11 class, we have below errors.

Lines: 19, 27, 36, 37

In Circle class, we have below errors

Lines: 21, 31, 42

In Oval class, we have below errors

Lines: 13, 15

Midweek_Week11.java

public class Midweek_Week11 {

// Begin Main Method

public static void main (String [ ] args) {

//Instantiate instances of subclasses

Circle cir = new Circle ( );

Circle oval = new Oval ( );

//Set value for circle

cir.setRad1 (21.5) ;

//Output data called from subclasses

System.out.println ("Circle Characteristic") ;

System.out.printf (" Radius: %.2f ", cir.getRad1 ( ) ) ;

System.out.printf ("Area: %.2f ", cir.calculateArea ( ) ) ;

//Set values for oval

oval.setRad2 (11.32) ;

//Output data called from subclasses

System.out.println (" Cube Characteristics") ;

System.out.printf (" Radius 1: %.2f ", oval.getRad1 ( ) ) ;

System.out.printf ("Radius 2: %.2f ", cir.getRad2 ( ) ) ;

System.out.printf ("Oval Area: %.2f ", oval.calculateArea ( ) ) ;

} //End Main Method

//End Class Midweek_Week11

}

Circle.java

import static java.lang.Math.*;
//Begin Subclass Circle
public class Circle {
//Class wide variable

private double rad1;
private double rad2;
//Set radius 1 method
public void setRad1 (double r1) {
rad1 = r1;
}//End set side method

//Get radius 1 method
public double getRad1( ) {
return rad1;
}
//End get side method

//Set radius 1 method
public void setRad2 (double r2) {
rad2 = r2;
}//End set side method

//Get radius 1 method
public double getRad2( ) {
return rad2;
}
//End get side method

//Calculate area method
public double calculateArea ( ) {
return PI * pow(rad1, 2);
}
}//End Subclass Circle

Oval.java

import static java.lang.Math.*;
//Begin Subclass Oval
public class Oval extends Circle{

/**
*Method to determine area of an Oval
*@return
*/
public double calculateArea ( ) {
return PI * (getRad1( ) * getRad2( ) );
}
} //End Subclass Oval

Output:

Circle Characteristic
Radius: 21.50
Area: 1452.20

Cube Characteristics
Radius 1: 0.00
Radius 2: 0.00
Oval Area: 0.00
