Description

When trying to convert the String "0085" to an Integer I get the following numberFormatException:

java.lang.NumberFormatException: For input string: "085"

Looking at the code reveals that only a null check is preformed before delegating to Integer#decode.

It would be nice if the NumberUtil classes create* Methods would offer some more support:

• remove leading and traling spaces.
• remove leading zeros.

Note: this would also be in line with NumberUtils#isNumber(String) - this method evaluates "0085" as true.
