How do you start a loop with an event and end the loop when u release ....

Question

How do you start a loop with lets say an event of some sort, whether it be holding down a key or pressing the mouse click and then stopping the loop when you release that key or mouse button.?
double c = 1.8, i = 1, max = 90, exp = 0;
final double inc = 0.002; //speed at while it increases
boolean f = false, g = false;
while (true)
    while (f == false && stopMeter == false) //increasing speed going up to 90
        exp = Math.pow (c, i);
        i += inc;
        pAngle.setText (Math.round (exp) + "");
        if (exp > max)
            f = true;
            g = false;
        } //end if
    } //end while
    while (g == false && stopMeter == false)  //decreasing speed going down from 90
        exp = Math.pow (c, i);
        i -= inc;
        pAngle.setText (Math.round (exp) + "");
        if (exp < 1)
            g = true;
            f = false;
        } //end if
    } //end while
} //end whilethis is a snippet of my increasing increments. Its for an angle meter. I can't get it to stop, when the user clicks or does something... the program just gets stuck in an infinite loop. I am still new to java and i do not know how to fix this.
