Java "100%" to number

Question

Is there a built in routine in Java that will convert a percentage to a number for example, if the string contains 100% or 100px or 100, I want a float containing 100.

Using Float.parseInt or Float.valueOf result in an exception. I can write a routine that will parse the string and return the number, but I'm asking does this already exist?

Answer 1

I think you can use:

NumberFormat defaultFormat = NumberFormat.getPercentInstance()
Number value = defaultFormat.parse("100%");
