joda time PeriodFormatter does not print years

I have a formatter as below: private static PeriodFormatter formatter = new PeriodFormatterBuilder() .printZeroNever() .appendYears().appendSuffix("...

The underlying problem here is your use of Duration to start with, IMO. A Duration is just a number of milliseconds... it's somewhat troublesome to consider the number of years in that, as a year is either 365 or 366 days (and even that... more 9/20/2016 7:29:36 AM

Argument1: Cannot convert from 'System.IO.Stream' to 'String'

I'm stumped on this, and could use some assistance. I've done web searches, and read documentation for the last several hours, and have had no luck. I'm getting an error that...

JObject.Parse takes a string, not a Stream. You're trying to pass it response, which is a Stream. To fix it, just use HttpClient.GetStringAsync instead, e.g. using (HttpClient client = new HttpClient()) { var response =... more 9/20/2016 7:21:50 AM

Integer gets automatically set to 0 C#

I am doing an exercise on making a small console program which shows how fast a car is moving and a function to make it go either faster or slower. So here is my class called...

Your Speed property is the problem. Here's the code: public int Speed //access private int speed { get { return speed; } set { speed = Speed; } } The getter is fine - it returns the value of the private variable. The setter,... more 9/19/2016 2:56:43 PM

Using random function in selecting an object if two same distance values

I have an ArrayList unsolvedOutlets containing object Outlet that has attributes longitude and latitude. Using the longitude and latitude of Outlet objects in ArrayList...

Note: I believe fabian's solution is superior to this, but I've kept it around to demonstrate that there are many different ways of implementing this... I would probably: Create a new type which contained the distance from the outlet as... more 9/19/2016 6:32:15 AM

How to convert digit month to the full name of month in C# console

I want to convert digit month that is inputed by User to the name of month. I find it easily to use if else condition, but is there any function I can use without using condition?...

There are two reasonably simple options: Construct a date using that number as the month, and then format it with a custom format, e.g. DateTime date = new DateTime(2000, month, 1); string monthName = date.ToString("MMMM"); Use... more 9/18/2016 3:46:46 PM

Java Cannot find symbol get.Method but Method is declared

I was given this class and told to fix errors and Finnish the class. For this assignment, you will need to develop a test driver and a comparable class. Luckily, Prof. Fuller...

This is the problem: public int compareTo(Object other) You've said you can compare this object to any other object. You can't call other.getMidi(), because getMidi() isn't a method declared on Object. I would suggest you change your... more 9/16/2016 9:27:06 PM

Java. How to test date created with LocalDateTime.now()

I have this class class MyObject { private LocalDateTime date; public LocalDateTime getDate() { return this.date; } public void myMethod() { this.date =...

I cannot mock now() because it is static Indeed - but fortunately, you don't have to. Instead, consider "a date/time provider" as a dependency, and inject that as normal. java.time provides just such a dependency: java.time.Clock. In... more 9/16/2016 9:19:20 AM

Peso Symbol in C#

if (num1 == 5) { Console.WriteLine("\nThe " + num2 + " kilo/s of {0} " + 28 + " per kilo ", "GRAPES"); Console.WriteLine("The total amount is {0}{1}",...

Sounds like you want to provide the culture en-PHI... although that isn't a valid culture name apparently. Perhaps you just want phi as the language? var culture = CultureInfo.GetCultureInfo("phi"); var text = string.Format(culture, "The... more 9/16/2016 8:20:29 AM

String in byte form to original string in java

I wrote a code writing 8 different values of sine in byte form (using .getbytes) into a text file. After I run it a file is created containing the following: [B@5f18cd5 ...

You can't. You've already lost all the important data. Calling toString() on a byte[] doesn't give you anything useful, because arrays in Java don't override toString()... so you're getting the implementation from Object, which just... more 9/16/2016 7:46:26 AM

Json.net serialize numeric properties as string

I am using JsonConvert.SerializeObject to serialize a model object. The server expects all fields as strings. My model object has numeric properties and string properties. I can...

You can provide your own JsonConverter even for numeric types. I've just tried this and it works - it's quick and dirty, and you almost certainly want to extend it to support other numeric types (long, float, double, decimal etc) but it... more 9/16/2016 7:40:08 AM
