public static long parseLong ( java . lang . String s ) throws java . lang . NumberFormatException { return parseLong ( s , 10 ) ; }
parses the string argument as a signed decimal long . the characters in the string must all be decimal digits , except that the first character may be an ascii minus sign ' - ' ( u002d ' ) to indicate a negative value . the resulting long value is returned , exactly as if the argument and the radix 10 were given as arguments to the method that takes two arguments . note that neither l nor l is permitted to appear at the end of the string as a type indicator , as would be permitted in java programming language source code .
