I cannot believe can start programming without knowing multiplication and division. As to understanding percents, I though elementary school is a prerequisite for doing programming.
Read at least something on programming, don't try to solve real problem if you did not do simple exercises.

i am not sure about java syntax but you can try something like this. its simple maths problem

JavaScript

var newamount = oldamount(origional amount) * 1(this is your percentage)/100;

you need to take care about decimal point precision or sometimes conversion from string to decimal may be.

hope this will help.

Hi,

Try this JavaScript

XML

<script type="text/ecmascript">
        function calculate()
        {
            var onePerc = amount * (percentage/ 100);
            alert(onePerc);
        }
    </script>

GoodLuck
