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

Here is my choose your own adventure project. There are no issues, apart after choosing this set of options (you don't have to read the whole thing):
1.name
2.no
3.hide, it asks you to input another answer.
It does not matter what you put in, the second time, as it will still run the program according to "hide". Just wondering why this is showing up. Also, feel free to enjoy my game.

I believe this is how you wanted it to run:
Ya arr a captain pirate on these high seas! Aboard the ship that yar father made, the M.M. Big Boy.
First order of business, is choosing your Pirate Name! What is yarr real name?
:me me big boy
Scupper that sailor! We'll call you Capn Cornelious Coxswain, The Hatless
Arr ye wondering why yer called Hatless? You have NO hats. So little amounts of hats. Literally 0 hats.
Yee and yer crew be lookin for any booty to steal, as well as gold and treasure!
'Look smartly Sir!' yells one of yer sailors. 'A darkness approaches starboard!'.
You look round the deck as yer biggest fear comes to life. A giant squid begins to wrestle the ship!
The crew starts to panic as the ship gets dragged into the water. 'Show a leg boys!' is the last thing you say before being dragged into the darkness.
She be lookin like the end for ol' Capn Cornelious Coxswain, The Hatless, until a giant sea turtle swims up to ye.
'I am King Randy Myrtle, The Friendly Sea Turtle.' Says Randy. 'I can take you to an island, climb aboard!'
Do you climb aboard King Randy Myrtle, The Friendly Sea Turtle? (Yes or No)
:no
'Well, SORRY for asking then.' says Randy. He swims away. Now you are sinking into the abyss. It doesn't look too good. When you look up, there is
a shark and it's eating your mates! You look up and see a raft, you look down and see a little cave you could hide in. Do you 'swim', or 'hide'?
:hide
You swim to the nearby cave. Inside is a beautiful mermaid. 'Hello' says the mermaid. You lean in to say hi, but you trip on a big, glossy, wet stack of the movie
'The Ocean of Trumpets'. There is at least sixty of them. 'Sorry!' you exclaim. 'Oh, that's okay. You've just stepped on my big, glossy, wet stack of my favorite movie,

that you could EASILY run away and STEAL a DVD. So, would you like to take a 'guess', or take a 'DVD'?
If yes, your problem was that you had your Third choice outside your check for the Second choice C2a.equalsIgnoreCase("swim"), and you put your else after C3b.equalsIgnoreCase("stay"). This caused your program to check if the second choice is swim, if yes print your text, else just take the third choice without printing. By placing the third choice into the second choice swim block, and fixing the else (C2a.equalsIgnoreCase("hide")) it runs correctly.

public ArrayList<String> new_contains_all= new ArrayList<>();
...
[[laying, beautiful, brushing, group, young, head, bed, close, couple, female, teeth, white, indoor, pair, holding, sunglasses, stuffed, wearing, posing, dress, person, hair, standing, looking, girl, red, playing, made, top, woman, lady, hat, clothing, goggles, people],
[person, hair, young, shirt, looking, phone, girl, white, glasses, food, sunglasses, wearing, woman, hat], [blue, beautiful, person, cake, standing, young, shirt, black, female, board, girl, white, photo, holding, ready, wearing, top, posing, woman, lady, smiling, clothing, dress, suitcase], [street, clock, light, stop, sign, red, text, sitting,
man, photo, traffic], [blue, person, young, looking, phone, sitting, female, girl, photo, computer, using, red, laptop, holding, glasses, food, sunglasses, wearing, top, woman, lady, hat]]
Notify that the Array have 5 elements inside.
Already tried this, that should be working for simple ArrayList but with more than 1 string per element its creepy, i know the solution must implement another bucle inside key, but so tired for today :/ maybe someone blinks my mind :P
List<String> l = new_contains_all;
Set<String> s = new HashSet<String>(l);
for (String key : s) {
int count = Collections.frequency(l, key);
if (count > 1)
System.out.println("Found '" + key + "' " + count + " times."+"key: "+key.toString()+"l: "+l.toString());
}

You almost solved your problem, but there is one subtle bug in your code:
Set<String> s = new HashSet<String>(l);
The core property of a Set is: it doesn't allow for duplicates. Thus this one call simply removes all duplicates from that input list l.
Thus: all frequencies will be one.
So, instead, you can do:
for (String singleWord: new_contains_all) {
count = Collections.frequency(new_contains_all, singleWord);
...

How do I print a random word from a string array? Java

I have to make the three arrays in my code (shown below) to print randomly. So for "Today:" and "Tomorrow" print a random good or bad comment. For your lucky and not so lucky days, print a random date and a random good comment for the lucky day and random bad comment for the not so lucky day. I don't know how to pick randomly from string arrays. I have this due tomorrow and I just started coding a few months ago so im not sure how I would go about doing this.
Today: You will meet an old friend!
Tomorrow: Trust your intuition. The universe is guiding your life.
Your lucky day for 2016 is November 4: You will win the jackpot.
Your not so lucky day for 2016 is January 24: Power failure day
This is my code:
String Month[]={"January","Febuary","March","April","May","June","July","August","September","October","November","December"};
String goodcomment[]={"None of the secrets of success will work unless you do","Today is a lucky day for those who remain cheerful and optimistic","You were born with the skill to communicate with people easily","The first step to better times is to imagine them","Trust your intuition. The Universe is your guiding light","It doesnt matter. Who is without a flaw?","Your happiness is interwined with your outlook on life","The secret of getting ahead is getting started", "Failure will never overtake you if my determination to succeed is strong enough.","What you do today can improve all your tomorrows.","In order to succeed, you must first believe that you can.","Always do your best. What you plant now, you will harvest later."};
String badcomment[]={"Power failure today","You'll miss the bus","Too many things to do and not enough time","University entranced denied","You'll lose your phone","You'll miss your date","You'll forget someone close to you's birthday", "Today is a disastrous day. If you can’t beat ’em, join ’em","You will meet someone next week that will bring negativity into your life","Don't step on a crack","You will wake up sad tomorrow","Your car will break down"};

You can use the Random class for this. The method nextInt(int bount) will return a random integer from 0 to bound-1.
So to randomly select a string from an array, you can do:
Random random = new Random();
int randomIdx = random.nextInt(goodComment.length);
System.out.println(goodComment[randomIdx]);

Solution will be obtaining selecting a random number from 0 or 1 to select randomly from good or bad comment (i.e. 0 – good comment and 1 – bad comment). Then selecting a comment randomly from the selected array by obtaining a random number from 0 to (length of the selected array – 1) in order to indicate the index of the printing comment. You can use the approach suggested by tixopi to generate the random number.
private String goodcomment[] = { "None of the secrets of success will work unless you do",
"Today is a lucky day for those who remain cheerful and optimistic"};
private String badcomment[] = { "Power failure today", "You'll miss the bus", "Too many things to do and not enough time",
"University entranced denied", "You'll lose your phone", "You'll miss your date"};
private Random indexGenerator = new Random();
public void printCommentWithPrefix(String prefix) {
System.out.println(prefix + " : " + selectRandomGoodOrBadComment());
}
private String selectRandomGoodOrBadComment() {
String randomGoodOrBadComment;
if (selectEitherGoodOrBad() == 0) {
randomGoodOrBadComment = selectAComment(goodcomment);
} else {
randomGoodOrBadComment = selectAComment(badcomment);
}
return randomGoodOrBadComment;
}
private int selectEitherGoodOrBad() {
int goodOrBadIndicator = indexGenerator.nextInt(2);
return goodOrBadIndicator;
}
private String selectAComment(String[] comment) {
int indexOfSelectedComment = indexGenerator.nextInt(comment.length);
String selectedComment = comment[indexOfSelectedComment];
return selectedComment;
}

JOptionPane variable might not have been initialized

I'm sorry the code is so long, I just need to know what I'm missing to initialize all my decisions. The compiler is complaining about my variable not being initialized. Thank you.

("You go left and hear a door open behind you, you panic and start to run\n"+
"you run intro different halls to try and escape but you trip. You just remembered that you have a sword with you and can now\n"+
"choose what to do 1. Take out sword and fight enemy 2. Get up and keep running.");
}
else
{
JOptionPane.showInputDialog(null,"You go right and get locked in behind you. You realize that there isnt anwhere to go\n"+
"and get lost in the darkest part of the castle and die alone.");
}

("You were able to fight of the armored enemy. But something tells you that that isnt the last of them. You continue on down the\n"+"hall and see from the distance to what seems to be your first prize. It cant be that easy.");
}
}
}

Define the decision variables as null. Instead of:
String decision1,decision2,decision3,decision4,decision5,decision6;
Define the variables as:
String decision1 = null;
String decision2 = null;
String decision3 = null;
String decision4 = null;
String decision5 = null;
String decision6 = null;

decision2 is only being set if decision1 is equal to 1. I think you want to put the if statements for the other decisions inside of each other like below:
if (decision1.equals("1"))
{
decision2 = JOptionPane.showInputDialog
("You find yourself at the entrance of the castle with a choice to go down a dark hall\n"+
"or to the closest room on the right side. Be vary wary the darkness can make you lose your mind and go insane and remember\n"+
"to keep track of were you are. 1. Into the room 2. Down the hall.");
if (decision2.equals("1"))
{
decision3 = JOptionPane.showInputDialog
("You step into the room and find some medication and a lantern with some oil.\n"+
"you also find a sword. You can choose now to go back to the dark hallway or to go down a hidden trap door in the room. It could be\n"+
"a shortcut or it could lead somewhere dangerous. 1. Back down the hall 2. Take your chances with the trapdoor.");
}
else
{
JOptionPane.showMessageDialog(null,"you should have looked in the room, you quickly lose your way and the darkness\n"+
"makes you crazy.");
}
}
else
{
JOptionPane.showMessageDialog(null,"You go back to your boring life in the town, you wont be remembered by anything and you\n"+
"lost your chance at getting the riches that lie deep in the castle. You lose.");
}

You must initialize your String variables (decision1, decision2,...) as:
String decision1 = null, decision2 = null, decision3 = null, decision4 = null, decision5 = null, decision6 = null;
Note that you don't get a compile error for decision1 because in the line
decision1 = JOptionPane.showInputDialog(...);
it is being initialized.
Also, your program's logic is bad. If decision1 is not 1, then you will just show a message, but the program will continue to check the next condition:
if (decision2.equals("1"))
where you will get a NullPointerException because you are comparing null with 1.

JOptionPane variable might not have been initialized
So keep in mind one thing that whenever you get such kind of error messages try to see that your variables are properly declared.
See when you try to use int variable it can give you error message if that variable is used in some computation. So try to initialize the variables like:
int a=0;
You can do the same thing with string variables also like:
String a=null;
Returning to answer
In your code you have just declared the variables , but the fact is that you have to actually initialize them.
Replace
String decision1,decision2,decision3,decision4,decision5,decision6;
By
String decision1=null,decision2=null,decision3=null,decision4=null,decision5=null,decision6=null;
