java.lang.Long parseUnsignedLong(String s))
Description
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.
Notes:
- 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.
Compatibility
Requires Java 1.8 and up
Java Long parseUnsignedLong(String s) Example
Below is a simple java example on the usage of parseUnsignedLong(String s) method of Long class.
package com.javatutorialhq.java.examples;
import java.util.Scanner;
/*
* This example source code demonstrates the use of
* parseUnsignedLong(String s) method of Long class
*/
public class LongParseUnsignedLongExample {
public static void main(String[] args) {
// Ask for user input
System.out.print("Enter a value:");
// declare a scanner object to read the user input
Scanner s = new Scanner(System.in);
// assign the input to a variable
String value = s.nextLine();
// get the parseUnsignedLong() method result
Long result = Long.parseUnsignedLong(value);
// print the result
System.out.println("Result:"+result);
// close the scanner object
s.close();
/*
* This method will yield the same result as that of the parseUnsignedLong(value,radix)
* if the radix is 10
*/
}
}
