Question

Starting Out with Java (6th Edition)

chapter 8, 3PC

Requirement: Each of the RoomCarpet and RoomDimension classes should have a toString method, an equals method, a copy method, and a copy constructor. The RoomCarpet class should have mutators and accessors for both of its fields.

Answer 1

The Code is:

import java.text.DecimalFormat;
public class Carpet {
private Dimension rmSize;
private pricesqft;
//constructor
public Carpet()
{
this.rmSize = new Dimension();
this.pricePerSqFt = 0.00;
}
public Carpet(Dimension rmSize, pricesqft)
{
this.rmSize = new Dimension(rmSize.getRmLength(),rmSize.getRmWidth());
this.pricePerSqFt = pricePerSqFt;
}
public Dimension getRmSize()
{
return new Dimension(rmSize.getRmLength(),rmSize.getRmWidth());
}
public double getPricePerSqFt()
{
return this.pricePerSqFt;
}
  
public void setRmSize(Dimension rmSize)
{
this.rmSize = new Dimension(rmSize.getRmLength(), rmSize.getRmWidth());
}
public void setPricePerSqFt(pricesqft)
{
this.pricePerSqFt = pricePerSqFt;
}
public double rmTotalCost()
{
return rmSize.getAreaRoom() * pricePerSqFt;   
}

public String toString()
{
DecimalFormat dollar = new DecimalFormat("$#,##0.00");
String str = this.rmSize.toString() + " Price per sq. ft : " +dollar.format(pricePerSqFt) + " Price to carpet Room: " + dollar.format(rmTotalCost()) + '\n';
return str;
}

public boolean equals(Carpet object2)
{
boolean status;
if ((this.equals(object2)==true)&&(this.pricePerSqFt==object2.pricePerSqFt))
status = true;
else
status = false;
return status;
}

}
