Question

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 need to allocate the array.

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