I'm programming a program that add feet and inch together(assume feet and inch are integer). I run into a compiler error. I know the problem is I'm missing the returning statement. But I don't know what to return.
public class Distance
{
private int feet;
private int inch;
public Distance()
{
}
public Distance(int ch, int ft)
{
feet = ft;
inch = ch;
}
public int getFeet()
{
return feet;
}
public int getInch()
{
return inch;
}
public void setFeet(int f)
{
feet = f;
}
public void setInch(int c)
{
inch = c;
}
@Override
public String toString()
{
return String.format("%d feet %d inch",getFeet(), getInch());
}
public Distance add(Distance d)
{
int i = getInch() + getInch();
int f = getFeet() + getFeet();
while (i>=12)
{
i = i-12;
f++;
}
setFeet(f)
setInch(i)
}
//public Distance subtract(Distance d)
//{
//}
}This is my constructor class. The compiler error mark the add method because it is missing the return statement. I know I specify return type is Distance, but if I return Distance it still mark at compiler error. I probably can change Distance to void, but my teacher specify using "public Distance add(Distance d)". What should I return here?
This is the main method class.
public class DistanceTest
{
public static void main(String[]args)
{
Distance d1 = new Distance(1, 5);
Distance d2 = new Distance(1, 5)
Distance d3 = d1.add(d2);
}
}
