Java Long parseUnsignedLong(String s) method example 2018-02-16T07:26:12+00:00

java.lang.Long parseUnsignedLong(String s))


The Long.parseUnsignedLong(String s) java method Compares two long values numerically. Parses the string argument as an unsigned decimal long. The characters in the string must all be decimal digits, except that the first character may be an an ASCII plus sign ‘+’ (‘\u002B’). The resulting integer value is returned, exactly as if the argument and the radix 10 were given as arguments to the parseUnsignedLong(java.lang.String, int) method.

Make a note that the parseUnsignedLong(String s) 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.parseUnsignedLong(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 parseUnsignedLong method non statically.


  • This method will throw NumberFormatException, if the string does not contain a parsable unsigned integer.

Method Syntax

public static long parseUnsignedLong(String s) throws NumberFormatException

Method Argument

Data Type Parameter Description
String s a String containing the unsigned long representation to be parsed

Method Returns

The parseUnsignedLong(String s) method of Long class returns the unsigned long value represented by the decimal string argument.


Requires Java 1.8 and up
