Distance Program

[patrick210]

Ok, the instructor has give explicit instructions to work with this code and make it work. I have most of it working, but I am hung up on the

public void add1 (int param5, int param6)
{
   Distance d2=d2.add (new Distance(param5, param6));
}

portion of the code. I am attaching the class below.

//*********************************************************************************
//Distance.java

public class Distance
{
	private int feet;
	private int inches;

	public Distance()
	{
		feet = 0;
		inches = 0;
	}
	public Distance(int param1, int param2)
	{
		feet = param1;
		inches = param2;
	}
	public Distance(Distance d)
	{
		feet = d.getFeet();
		inches = d.getInches();
	}
	public int getFeet()
	{
		return feet;
	}
	public int getInches()
	{
		return inches;
	}
	public void setFeet(int param3)
	{
		feet = param3;
	}
	public void setInches(int param4)
	{
		inches = param4;
	}
	private int toInches()
	{
		 return feet * 12 + inches;
	}
	public void add (Distance distance)
	{
		int totalInches = toInches() + distance.toInches();
		feet = totalInches / 12;
		inches = totalInches % 12;
	}

	//--------------------------------------------------------------------------
	//method takes 2 integer parameters representing a distance in feet and
	//inches.

	//--------------------------------------------------------------------------
	public void add1 (int param5, int param6)					//creates local Distance object & passes it to the other
																//add method
	{
	 	Distance d2 = d2.add new Distance(param5, param6);	//adds parameter's distance to the current
																//distance ensuring that the result is
																//correct & that inches is between 0-11
	}
	public String toString()
	{
		return feet + "\'" + inches + "\"";
	}
}

please help.

Hi,

Method add should be defined with the return type Distance.
and return the Distance object within the add method definition.
Make the following changes in ur code.

public Distance  add (Distance distance)
	{
		int totalInches = toInches() + distance.toInches();
                          Distance d=new Distance();
		d.feet = totalInches / 12;
		d.inches = totalInches % 12;
                          return d;

	}
