Set Min and Max Value for Int? Android

Is there a way to set minimum and maximum value of an integer? I did some research but I couldn't find anything useful. I need to set min value 0 and max value 30, so when user is touching button(TouchListener) numbers will go from 30 to 0. I know it can be done with if else statements but I am looking for a better way.

     int total= Integer.MAX_VALUE + 30;
     int left= Integer.MIN_VALUE + 0;

        total= 30;
        left = 30;
            .....
    onTouchListener...
    switch (action) {
                case MotionEvent.ACTION_DOWN:

    left--;
    setText();
break;
    ...
protected void setText() {
    count.setText(left + "/" + total);
}

But the problem is, int value goes under 0. -1 -2 etc etc How can I stop this? How to set Min int value?

You can use the range seek bar which allow you to seek between two specific integer values.

Try to check left value before decrees by 1 :

if(left < 0){
   left--;
   setText();
}

Replace left--; with the following: 

left -= (left > 0 ? 1 : 0);
