Method Details

isCreatable

public static boolean isCreatable(String str)

Checks whether the String a valid Java number.

Valid numbers include hexadecimal marked with the 0x or 0X qualifier, octal numbers, scientific notation and numbers marked with a type qualifier (e.g. 123L).

Non-hexadecimal strings beginning with a leading zero are treated as octal values. Thus, the string 09 will return false, since 9 is not a valid octal value. However, numbers beginning with 0. are treated as decimal.

null and empty/blank String will return false.

Note, createNumber(String) should return a number for every input resulting in true.

Parameters:

str - the String to check

Returns:

true if the string is a correctly formatted number
