You can do this by implementing the For class' toString method:

public String toString ( )
{
    return "your parameters: " + a + ", " + b + ", " + c;
}

You would have to override the toString() method and create another one that prints out the contents of r1.

@Override
public String toString(){
    return a + ", " + b + ", " + c;
}

Then it is simply:

System.out.println("Your parameters: " + r1.toString());

Add a toString method in For as:

@Override
public String toString(){
    return "your parameters: "+ a + ", "+ b+ ", "+c;
}
