Question

This is a debugging question - 

The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly.

Code I was given -

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