Howdy yall, I have a little problem. I can't use instance variables and i need to pass by reference. So i can't use primitive data types since they are not passed by reference. I wrapped them up in a wrapper class. I have two Integer types that i send to a method. Once its in the method everything is fine. In the method i sent it to, i send it to another method as Integer (the same wrapper) so there is no change its still a wrapped integer. I do my logic on it and change its value...at the end of that method i check the value. It has value, some number that changes everytime(as it is suppose to do). However right after i check the value, i have a return. Right after i return, the values are reset to 0. But they are wrapped in a class. They should be sending by reference. Take a look at this example that demonstrates the situation.
void main()
{
//
Integer intOne;
Integer intTwo;
firstMethod(intOne, intTwo);
}
void firstMethod(Integer intOne,Integer intTwo)
{
//display stuff
...
getValues(intOne, intTwo);
//right after we return
//display Integers
//they are 0 now :(
}
void getValues(Integer intOne,Integer intTwo)
{
//display the integers...everythings good
//do stuff, change values
//right before we return...display new values...yay the Integers have changed
return;
}
