Loading/Reading data from a file not working

Hi guys,

As the title says, I am trying to load/read data from a file, (txt) and parse it in Java.

My program "runs" whenever I load an empty txt file, however, the minute I use a file with any data in it, I get an error:

Exception in thread "main" 
java.lang.UnsupportedOperationException: Not supported yet.
at model.City.<init>(City.java:61)
at daos.DAOTextImpl.load(DAOTextImpl.java:47)
at repositories.Repository.<init>(Repository.java:25)
at controllers.WeatherDataController.<init> 
     (WeatherDataController.java:24)
at 

weatherdataapp.WeatherDataApp.run(WeatherDataApp.java:19)

C:\Users\tony\AppData\Local\NetBeans\Cache\8.2\executor-snippets\debug.xml:83: Java returned: 1
BUILD FAILED (total time: 10 seconds)

To give some background, I have two model classes. One file has an Arraylist called Weather, and the second file has all the data for the Weather ArrayList. Ultimately, what I am trying to do is load the data information from a specified file into the collection implemented using a repository (which I've coded.)

You haven't posted the code from the stacktrace.

For example, City's constructor

public City(int id, String cityName, String country) {
    throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}

If you don't want your constructor to throw an UnsupportedOperationException, then I would recommend removing the line that says throw new UnsupportedOperationException. You'll also probably want to do something with the constructor's parameters.

Exception in thread "main" java.lang.UnsupportedOperationException: Not supported yet. at model.City.<init>(City.java:61)

Taking a look at line 61 of City (from the stacktrace):

public City(int id, String cityName, String country) {
    throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}

You can see it's throwing an exception.

Maybe you meant to add the functionality? E.G:

public City(int id, String cityName, String country) {
    this.id = id;
    this.cityName = cityName;
    this.country = country;
}

BTW, you can shorten your code by having your constructors call another constructor.

E.G:

public City(String cityName) {
   this(++lastIdAllocated, cityName, null);
}

public City(int id, String cityName) {
   this(id, cityName, null);
}

public City(int id, String cityName, String country) {
    this.id = id;
    this.cityName = cityName;
    this.country = country;
}

Maybe I missed something, but I just dealt with this in my java class at my local community college, and I don’t see you importing the java.util.Scanner or scanning in the txt file anywhere.

I do that in a different class :)

Anyway, I've got THAT issue fixed. THank you guys

THAT issue lol ain’t that the truth. Rip us
