Put items in a string array?

I have a little question. I want to put some strings in an String[]. How can I do this?

I tried 

String[] categorys;
for (int i = 0; i < jArray.length(); i++) {
                        JSONObject jsdata = jArray.getJSONObject(i);
                        String myString = jsdata.getString("id_category");
                        String namecategory = jsdata.getString("category_name");
                        System.out.println("Category name" + namecategory);
                        categorys[i] = namecategory;
                    }

but I get 07-28 16:40:01.719: ERROR/AndroidRuntime(452): Caused by: java.lang.ArrayIndexOutOfBoundsException

I don't know how to use an array of Strings. Need some help.Thanks...

You're trying to set the value of an element of the array which doesn't exist (your array has no elements). You need to initialize the length of the array.

You need to allocate the array.

String[] categorys = new String[jArray.length()];
