Overloaded Methods

[eranga262154]

Hi...

I want to create 3 overloaded methods for the following code block.

int i1 = 11;
int i2 = 5;
int iTotal = addNumbers(i1,i2); // method 1
System.out.println("iTotal: "+iTotal);

double d1 = 12.0;
double d2 = 3.9;
double dTotal = addNumbers(d1,d2); // method 2
System.out.println("dTotal: "+dTotal);

double mixedTotal = addNumbers(i1,d1); //method 3
System.out.println("mixedTotal: "+mixedTotal);

I done it as follows,

class OverloadMethods
{
public static void main(String args[])
{
int i1 = 11;
int i2 = 5;
int iTotal = addNumbers(i1,i2); // method 1
System.out.println("iTotal: "+iTotal);
double d1 = 12.0;
double d2 = 3.9;
double dTotal = addNumbers(d1,d2); // method 2
System.out.println("dTotal: "+dTotal);
double mixedTotal = addNumbers(i1,d1); //method 3
System.out.println("mixedTotal: "+mixedTotal);
}
static int addNumbers(int i1,int i2)
{
return i1 +i2;
}
static double addNumbers(double d1,double d2)
{
return d1 + d2;
}
static double addNumbers(int i1,double d1)
{
return (double)i1 + d1;
}
}


It’s ok for me. Now what I want to do it need to write a 4th method, let say orderedOutput() that take three totals as parameters (iTotal,dTotal,mixedTotal) and displays them from greatest to least.

I’m confusing how to display all these three totals in a single method. Please can someone help on this?

[ComputerJy]

static void orderOutput(double v1,double v2, double v3){}

total is a value not an object you know , and since the parameters could be either a double or an integer, go with the larger memory block

Its ok,

What I want to know is how to return three parameters through a singlel method.

you can set them as class attributes or pass objects instead of values (Integer instead of int...)

The primitive wrappers are immutable. Pass arrays with one element or custom wrappers.

That you mean, first ordered three elemwnts and store in a array, from the order what I want. Then return that array. Isn't it?
