You could make a method in your parameters class called getCalculator, which simply returns the calculator -

public Calculator getCalculator()
{
return calc;
}

Then create an instance of parameters in intake and call the getCalculator method upon it.

Parameters pram = new Parameters();
Calculators calc2 = new Calculators();
calc2 = pram.getCalculator();

Hopefully that will help.

I think what you have is an issue of scope.

Looking at the above, I think you placed the getCalculator method in the wrong class. It should go in the Parameters Class.

So you would have the following:

Java Syntax (Toggle Plain Text)

public class Parameters{
   Calculations calc = new Calculations();
   //some calculations done using variables in the calculations class 
   //and new data is saved 
 
   public Calculations getCalculator() {
      return calc;
   }
} //end of Parameters.class
 
public class Intake{
   // I now want to work with the instance "calc" created above so I can 
   // use the variables that were set in Parameters.class, but I don't know
   // how to reference this instance!!
   Parameters pram = new Parameters();
   Calculators calc2 = new Calculators();
   calc2 = pram.getCalculator(); 
}

public class Parameters{ Calculations calc = new Calculations(); //some calculations done using variables in the calculations class //and new data is saved public Calculations getCalculator() { return calc; } } //end of Parameters.class public class Intake{ // I now want to work with the instance "calc" created above so I can // use the variables that were set in Parameters.class, but I don't know // how to reference this instance!! Parameters pram = new Parameters(); Calculators calc2 = new Calculators(); calc2 = pram.getCalculator(); }

Opps, I mispelled, Calculations

The second class should be:

(Toggle Plain Text)

public class Intake{
   // I now want to work with the instance "calc" created above so I can 
   // use the variables that were set in Parameters.class, but I don't know
   // how to reference this instance!!
   Parameters pram = new Parameters();
   Calculations calc2 = new Calculations();
   calc2 = pram.getCalculator(); 
}

public class Intake{ // I now want to work with the instance "calc" created above so I can // use the variables that were set in Parameters.class, but I don't know // how to reference this instance!! Parameters pram = new Parameters(); Calculations calc2 = new Calculations(); calc2 = pram.getCalculator(); }

Also I suspect you have Calculations defined somewhere?
