Java long decode() method example 2018-02-16T07:26:14+00:00

java.lang.Long decode(String nm)


The Long.decode(String nm) java method decodes a String into a Long. Accepts decimal, hexadecimal, and octal numbers given by the following grammar:

<strong>DecodableString:</strong>Signopt DecimalNumeralSignopt 0x HexDigitsSignopt 0X HexDigitsSignopt # HexDigitsSignopt 0 OctalDigits<strong>Sign:</strong>-+

Make a note that the decode() method of Long class is static thus it should be accessed statically which means the we would be calling this method in this format:

Long.decode(method args)

Non static method is usually called by just declaring method_name(argument) however in this case since the method is static, it should be called by appending the class name as suffix. We will be encountering a compilation problem if we call the java decode method non statically.


  • this method throws NumberFormatException, if the String does not contain a parsable long.
