Explanation / Answer

Hi, I have fixed it.

// Instantiates Rowboat
// Rowboat is child of Boat
class DebugEleven1
{
public static void main(String[] args)
{
DebugRowboat myBoat = new DebugRowboat();
System.out.println(myBoat.toString());
}
}
  
class DebugRowboat extends DebugBoat
{
public DebugRowboat()
{
super("row");
setPassengers();
setPower();
}
public void setPassengers()
{
super.passengers = 2;
}
public void setPower()
{
super.power = "oars";
}
}
  
abstract class DebugBoat
{
String boatType = new String();
int passengers;
String power = new String();
public DebugBoat(String bt)
{
boatType = bt;
}
// override equals() method to satisfy
// requirements of Debug Exercise 3.
public boolean equals(DebugBoat otherBoat)
{
boolean result;
if((passengers == otherBoat.passengers) && (power.equals(otherBoat.power)))
result = true;
else
result = false;
return result;
}
public String toString()
{
return("This " + boatType + "boat carries " + passengers +
" and is powered by " + power);
}
public abstract void setPower();
public abstract void setPassengers();
}

/*

Output:

This rowboat carries 2 and is powered by oars
