Sort an array of instances of a custom class based on a field

I'm having a problem right now in a project that I'm making just to learn more about java, so I have a txt file which has wonders, I'll have to read it and then store it different information in a object (name country, heightdepth, accessibility, hostility, kmfromlondon, temperature, wondervalue and a fact about the wonder), then I have to sort by the hostility rate and output the all of the wonders
here's the txt file of the wonders:
Amazonia,Brazil,60,10,10,8100,30,4,The Amazon rainforest occupies some 5.5 million square kilometres of South America.
Iguassu Falls,Brazil|Argentina,82,11,50,10064,25,4,Two hundred and seventy waterfalls flow along nearly 3 kilometres of rivers.
Niagra Falls,USA|Canada,50,18,69,5804,20,4,Adventurous tourists can take a cruise on the river below into the falls' mist.
Giant's Causeway,Northern Ireland,12,19,17,592,15,2,Legend has it that is is a former 'walkway' to Scotland.
Great Barrier Reef,Australia,60,10,10,15292,28,4,Over 30 species of whale and 15000 species of fish live here.
Mount Everest,Tibet|Nepal,8840,7,95,7424,-10,4,The highest mountain on Earth is located in the Himalayas.

Ngorongoro Crater,Tanzania,610,14,19,5804,30,2,Home to almost 25000 animals including masses of flamingoes around Lake Magadi.
Perito Morena Glacier,Argentina,60,9,82,13230,-5,3,The 5 kilometre wide glacier is well known for its process of rupturing.
Mount Fuji,Japan,3776,13,69,8671,25,2,Although classed as active its last eruption was in 1707.
Mont Blanc,Italy|France,4808,18,85,808,0,2,The highest mountain in Europe and a popular skiing destination.

Grand Canyon,USA,1600,15,80,8296,30,4,A vast and breathtaking spectacle stretching across the Arizona desert.
so I created an object like this
public class Wonders {
String name;
List countries = new ArrayList();
int heightDepth;
int accessibility;
int hostility;
int kmFromLondon;
int temperature;
int wonderValue;
String fact;
List compare = new ArrayList();
and then I stored it like this
String unftxt[];
unftxt = new String[24];
Wonders w[] = new Wonders[unftxt.length];
try (Scanner sfile = new Scanner(new File(fName))) {
while(sfile.hasNextLine()){
unftxt[ctrl] = sfile.nextLine();
ctrl++;
}//end while .hasnextLine()
}//try
for(int i=0;i<unftxt.length;i++){
String[] parts = unftxt[i].split(",");
w[i] = new Wonders();
w[i].name = parts[0];
w[i].countries.add(Arrays.toString(parts[1].split("\\|")));
w[i].heightDepth = Integer.parseInt(parts[2]);
w[i].accessibility = Integer.parseInt(parts[3]);
w[i].hostility = Integer.parseInt(parts[4]);
w[i].kmFromLondon = Integer.parseInt(parts[5]);
w[i].temperature = Integer.parseInt(parts[6]);
w[i].wonderValue = Integer.parseInt(parts[7]);
w[i].fact = parts[8];
}
I'm new in programming and I've been stuck for a while now so my question is how can I sort this array by hostility

The regular way to define a custom ordering in Java is via a Comparator instance. This object can be plugged into the sorting routines of eg Arrays or Collections.
In Java 8 for example you can sort your array like so:
Arrays.sort(wonderArray, Comparator.comparingInt(wonder -> wonder.hospitality));
In Java 7 or before, you can do it with an anonymous class:
Arrays.sort(wonderArray, new Comparator<Wonder>() {
#Override public int compareTo(Wonder w1, Wonder w2) {
return Integer.compare(w1.hospitality, w2.hospitality);
}
});

Eclipse android IndexOutOfBounds

currently i dont know what im doing wrong here is my sample code please help me
Problem:

Lastly let me add that i havent put the last details on index 100-150 our if fits realy index sorry if im stupid or sound stupid im fairly new ot this im really sorry.

Test instances always classified in to the the same class

I have written a java program that build a J48 classifier using training set. Then I pass a test instance to the classifier to predict the unknown class. But each and every test instance classified in to first element of the class attribute.
example : - if I declare element of class attributes,
cls.add("positive");
cls.add("negative");
In this order, each instance classified in to first class element which is positive.
If I declare class element in this order,
cls.add("negative");
cls.add("positive");
each instance classified in to first class element which is negative.
My training set shows more than 90% accuracy in weka explore.
public static void main(String[] args) throws Exception {
StringToWordVector filter = new StringToWordVector();
//training set
BufferedReader reader;
reader = new BufferedReader(new FileReader("D:/suicideTest.arff"));
Instances train = new Instances(reader);
train.setClassIndex(train.numAttributes() -1);
filter.setInputFormat(train);
train = Filter.useFilter(train, filter);
reader.close();
J48 nb = new J48();
nb.buildClassifier(train);
ArrayList cls = new ArrayList(2);
cls.add("positive");
cls.add("negative");
Attribute clsAtt = new Attribute("class", cls);
//ArrayList<String> tweet = new ArrayList(1);
//String tweet = "";
//Attribute tweetAtt = new Attribute("tweet", tweet);
ArrayList allAtt = new ArrayList(2);
//allAtt.add(tweetAtt);
allAtt.add(new Attribute("tweet", (FastVector) null));
allAtt.add(clsAtt);
// Create an empty test set
Instances testSet = new Instances("", allAtt, 1);
// Set class index
testSet.setClassIndex(testSet.numAttributes() - 1);
String names= "Fox News Devotes a Whole Evening[']s Worth of Programming to Whining About CNNAgain (column by #justinbaragona)";
Instance inst = new DenseInstance(2);
inst.setValue((Attribute)allAtt.get(0), names.toString());
testSet.add(inst);
System.out.println(testSet.instance(0).toString());
double pred = nb.classifyInstance(testSet.instance(0));
filter.setInputFormat(testSet);
testSet = Filter.useFilter(testSet, filter);
String predictString = testSet.classAttribute().value((int) pred);
System.out.println(predictString);
}
my training set look like
#RELATION suicidalideation
#ATTRIBUTE tweet string
#ATTRIBUTE class {positive,negative}
#DATA

HashMap: sorting key into alphabetical order with it's mapped values

I asked a question here a while ago, fixed it, but now I have run into another problem.
This is jumblesOrdered ArrayList: [act, opst, dgo, art, aprt, fgor]
This is jumbles ArrayList: [atc, otsp, gdo, atr, arpt, grof]
This is dictionaryOrdered ArrayList: [act, act, act, dgo, dgo, opst, opst, opst, opst, opst, opst, art, art, art, aprt, aprt, aprt, fglo, fglo, fgor, gopr, glos]
This is dictionary ArrayList: [act, cat, tac, dog, god, post, pots, stop, spot, tops, opts, rat, tar, art, trap, tarp, part, flog, golf, frog, gorp, slog]
This is jumbleWordHM: {opst=otsp, art=atr, fgor=grof, aprt=arpt, dgo=gdo, act=atc}
This is dictWordHM: {opst=post pots stop spot tops opts, art=rat tar art, glos=slog, gopr=gorp, fgor=frog, aprt=trap tarp part, dgo=dog god, act=act cat tac, fglo=flog golf}Current Output:
Current Output:
atc act cat tac
otsp post pots stop spot tops opts
gdo dog god
atr rat tar art
arpt trap tarp part
grof frog
Desired Output:
arpt part tarp trap
atc act cat tac
atr art rat tar
gdo dog god
grof frog
otsp opts post pots spot stop tops
My code for printing out current output:
for (int i = 0; i < jumblesOrdered.size(); i++) {
String wordAnswer = jumblesOrdered.get(i);
System.out.println(jumbles.get(i) + " " + dictWordHM.get(wordAnswer));
}
The first word of each line is the scrambled word, and the subsequent words are the dictionary words that can be made from the scrambled letters.
My only problem is that I want to organize the scrambled words into alphabetical order like:
arpt - dictionary words
atc - dictionary words
atr - dictionary words
etc.....

HashMap cannot be sorted, you should use some kind of a sorted map, like TreeMap, but maps can only sort by keys. (TreeSet could also be beneficial, it only takes a key and sorts them automatically.)

Consider using a TreeSet or TreeMap, which automatically use natural ordering on their elements.
Probably a TreeMap where the key is element 1, and the value is the ArrayList the element comes from. (A TreeSet is basically a TreeMap with only a key--no value.)

Java midi note to string mapping via octave of a note

In my project I want to be able to at least inform the user what string the note they need to play is on. I can get the note and its octave but as I've discovered, that note and its octave can appear in multiple places on a guitar fret board.
So my question is: Is there anyway to map a midi note to a guitar string?

Here's code that takes the MIDI note value and returns the position on the guitar fretboard closest to the end of the instrument. Fret zero is an open string.
static class Fingering {
int string;
int fret;
public String toString() {
return "String : " + stringNames[string] + ", fret : " + fret;
}
}
static String[] stringNames = new String[] {"Low E", "A", "D", "G", "B", "High E"};
/** Array showing guitar string's relative pitches, in semi-tones, with "0" being low E */
static int[] strings = new int[]{64, 69, 74, 79, 83, 88};
public static Fingering getIdealFingering(int note) {
if (note < strings[0])
throw new RuntimeException("Note " + note + " is not playable on a guitar in standard tuning.");
Fingering result = new Fingering();
int idealString = 0;
for (int x = 1; x < strings.length; x++) {
if (note < strings[x])
break;
idealString = x;
}
result.string = idealString;
result.fret = note - strings[idealString];
return result;
}
public static void main(String[] args) {
System.out.println(getIdealFingering(64)); // Low E
System.out.println(getIdealFingering(66)); // F#
System.out.println(getIdealFingering(72)); // C on A string
System.out.println(getIdealFingering(76)); // E on D string
System.out.println(getIdealFingering(88)); // guitar's high e string, open
System.out.println(getIdealFingering(100)); // high E, 12th fret
System.out.println(getIdealFingering(103)); // high G
}
Result:
String : Low E, fret : 0
String : Low E, fret : 2
String : A, fret : 3
String : D, fret : 2
String : High E, fret : 0
String : High E, fret : 12
String : High E, fret : 15

Yes, with simple logic you can do this. I would consider using a HashMap of <Note, MidiNote> where Note is your class that holds both relative note and octave and has decent equals and hashcode methods, and MidiNote is your class to represent a Midi note.

Think of MIDI as like defining piano keys. Codes and keys are one-to-one. This is unlike a guitar or violin, where the same tone can be played in multiple places.
If you want to represent the greater freedom you have on a guitar in some data format, you'll have to find or invent a different format. MIDI won't encode what you want.
However, there's an indirect way you might go about this, and it has to do with developing heuristics as to where to play a note given a sliding window of notes that came before. A given note may be easier on one string or another depending on what you've just played, and you can calculate that given a model of the hand and where fingers will have been. Based on this, you can convert MIDI to guitar in a way that makes the MIDI easiest to play. If you have a piece of guitar music that follows these rules already, then you can encode it in MIDI and then decode it later.
But perhaps your question is more basic. Yes, you can map a MIDI note to a guitar. The naive method is to make a mapping of each note playable on the guitar, and you decide between equivalent alternatives by picking the one closest to the nut. This would be an easy one-to-one mapping but wouldn't necessarily be the easiest to play.
If you REALLY want to do it right, you'll do a careful analysis of the music to decide the optimal hand position and where the hand position should change, and then you'd associate MIDI notes with frets and strings based on what's easiest to reach based on the hand position. The optimal solution is probably NP-complete or worse, do you'd probably want to develop an approximate solution based on some rules about how often and how far you can change hand position.
