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";
}
}

- This is a debugging question I am struggling on - 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 - public class DebugCustomer { protected int idNumber; protected String name; protected double creditLimit; public DebugCustomer(int id, name, double creditLimit) { idNumber = id; name = name; creditLimit = credit; } public void display() { System.out.println("Customer # + idNumber + Name: " + name, "\nCredit limit $" + creditLimit); } } ----- public class DebugCustomerMakingPurchase extends DebugCustomer { private double amountOfPurchase; private boolean overLimit; public DebugCustomerMakingPurchase(int id, String name, double credit, double purchAmount) { amountOfPurchase = purchAmount;…arrow_forward3. Consider the following two classes and write down the output of the following code: public class Test extends G{ void display() { String s = m1(); System.out.println("My name is "+ s); i - 7; j = j + i; } void show(){ System.out.println(" j value is - } public static void main(String args[]) { Test t - new Test(); System.out.println("s value is = t.display(); t.i = 9; System.out.println("i value in the object="+t.i); System.out.println("j value in the object="+t.j); t.show(); } abstract class G{ String s - "Exam"; int i = 10; int j - 5; String m1(){ s = "Java"; return s; abstract void display(); abstract void show( ); } " + j); + t.s);arrow_forward
