I have no idea what is wrong with this code

[Renee Crozier]

I have no idea what is wrong with this. I keep trying to compile it but I keep getting this error.....
"Error: invalid method declaration; return type required"

Any help would be greatly appreciated. I'm new to java and it's so frustrating.

Thanks!!!


public Pair(double aF, double aS)
{
aFirst = aF;
aSecond = aS;
}

public double getFirst()
{
return aFirst;
}

public double getSecond()
{
return aSecond;
}

Hi Renee,

It says return type required, and out of the three methods only one has no return type.

public Pair(double aF, double aS){
   aFirst = aF;
   aSecond = aS;
} 

HINT:
I am unsure what your code is to do as it's not complete, but if everything else is good it could be rectified with a word in line 1.

edit. unless Pair is also your class name which it appears to be with the naming convention.

cheers,
Daniel

Welcome to the Ranch.

public Pair(double aF, double aS) 
{ 
    aFirst = aF; 
    aSecond = aS; 
} 

Like Daniel rightly said, this looks like a constructor.
If that is the case, what is the name of your java class?
Since Java is case sensitive, it should be Pair (and not pair)

If you have defined it as pair (with a lower case p) the compiler thinks public Pair(..) is a method which is lacking a return type and complains accordingly
