Thread: Changing from Public to private

So I have some code here, and I want to change the "reactionFactor" variable in "ReactionAgent" to private or protected and still be able to access it in the next class "Augmentium"
when i cahnge it to private it tells me that i cant access it because It is private.. I dont want the rectionFactor variable to be changed in the "ReactionAgent" class, only in the instance in the "Augmentium" class.


I panic so much when I cant get these things done. Im new to java and im wondering if i should just switch to another major or dropout ....I appreciate all help


Here are the two classes:

package ReactionAgent;
 
public class ReactionAgent 
{
	public int reactionFactor;  //I want this to be private 
 
	public ReactionAgent()
	{
	reactionFactor = 1;
	}
 
	public void setFactor (int Factor)
	{
	reactionFactor = Factor;
 
	}
 
	public int getFactor()
	{
	return reactionFactor;
	}
 
 
 
 
}

 
 
 
import ReactionAgent.ReactionAgent;
import java.util.Random; // import this library
public class Augmentium
{
	private int val;
	private int max; 	
	private int nextInt;
	public void Augmentium()
	{
	val = 1;
	max = 4;
	nextInt = 1;
	}	
 
 
 
 
 
	ReactionAgent Augmentium = new ReactionAgent();
	/*public int oreReaction(int Ore)
	{
	Ore = reactionFactor + Ore;
	return Ore;
	}*/
 
 
 
 
	Random randNum = new Random();
 
 
	public int randNum()
	{
	max = 3;
 
 
	Augmentium.reactionFactor = randNum.nextInt(max) + 2; //gets a value between 2 and max(inclusive)
	return Augmentium.reactionFactor;
	}	
 
 
	 public static void main(String args[])
    {
        Augmentium test = new Augmentium();
		System.out.println(test.randNum());
 
 
   }

Can you use getter and setter methods to allow access to the value in the variable?

Please edit your post and wrap your code with code tags:

[code]
**YOUR CODE GOES HERE**
[/code]

to get highlighting and preserve formatting.

Use a getter method to access the value of variable.
Use a setter method to set the value of the variable.

See the ReactionAgent class.
It has a getFactor method
and a setFactor method.

An example:

   refToClass.setValue(newValue);    //  set the Value to newValue
   value = refToClass.getValue();     //  get the Value
