hi !

you can only return a single object in java.
however you can return a compound object.

in your case :

class Couple{
  public int a;
  public int b;
}

Couple Do_A_Test (int a, int b)
{  
  Couple cpl = new Couple();

   cpl.a= 4;
   cpl.b= 5;    
   return cpl;  
}

OR

Couple Do_A_Test (Couple cpl)
{  
  Couple cpl = new Couple();

   cpl.a= 4;
   cpl.b= 5;    
   return cpl;  
}


in Java ALL variables are references. the only exception are the basic types : byte, int, char, float, double long etc.. but not String. Basically all types that are objects have their type(or class) name starting with upper case. Long,Double,String, etc are objects (accessed by reference then...) BUT double, float, int etc are not and are passed by value.

for instance:

String str1="abc";
String str2="123";

str2=str2;//java affects by reference only !
str1="blahblah";

System.out.println(str2); //this will print "blahblah" and not "abc" !


cheers !
