String array won't add string in a for loop

I am tryiing to make a hangman game in Java, but I am having problems initializing a variable lStorage. I have added String[] lStorage,but still not initializing.

switch(difficulty){
    case 0:
        String[] easywords= new String[]{"integer","project","octopus"};
        int wrong = 12;
        String[] lStorage;
        String easyrnd = (easywords[new Random().nextInt(easywords.length)]);
        System.out.println("The word has " + easyrnd.length() + " Letters");
        while(wrong>=0){
        System.out.println("\n guess a letter");
        String letterguess = consolereader.nextLine();

        if(easyrnd.contains(letterguess)){
            System.out.println("correct " + letterguess + " is the " + "...number" + "Letter"); //need to put in number of letter
            for(int i=12;i>0;i--){
                lStorage[i]=letterguess;
            }

In Java, arrays are objects (like in C# and probably many other object oriented languages). So, you must create/initialize them using the new keyword.

The array actually hasn't been initialized. What you've done is declared it. Try something like this:

String[] lStorage = new String[size];

If this array has to be dynamically sized, I would suggest using a java.util.List or another collection class.

You need to initialize your String array

Try to change this line

String[] lStorage;

to this one

String[] lStorage = new String[12];
