Array String Declaration

Question

I have a frustrating issue which could be easy  Arrays in java seem to be frustratingly not intuitive   I have an String array called title it has several titles  here is part of the array      private String   title              Abundance            Anxiety            Bruxism            Discipline            Drug Addiction          This part seems OK in as the code compiles and runs just fine now I want to create another array BASED on this array  the new arrays will be made static text concatenated with data from this array and then more static text   I define the two static strings      String urlbase    http   www somewhere com data        String imgSel     logo png     so i added the declaration for the new array      String   mStrings    and then I create a basic for loop to iterate through and create the elements of the new array      for int i 0 i lt title length i              mStrings i    urlbase   title i  replaceAll    a-zA-Z        toLowerCase     imgSel          the loop takes the array value and strips out non alpha chars and makes it lowercase thus   Drug Addiction  becomes   drugaddiction  I want to end up with something like this  mStrings 0   http   www somewhere com data abundance logo png  mStrings 1   http   www somewhere com data anxiety logo png  mStrings 2   http   www somewhere com data bruxism logo png  mStrings 3   http   www somewhere com data discipline logo png  mStrings 4   http   www somewhere com data drugaddiction logo png    I tried several different attempts at declaring mStrings but all were incorrect when I leave it out Eclipse suggests this   String   mStrings     Now this seems like it should be fairly easy and correct but when I enter anything after it I get an error that says    Syntax error on token        expected after this token   Since it is one to one with the other array I tried this in the declaration but it also fails      String   mStrings title length       just to give it a quantity  I am thinking the error is someplace in the declaration but I can t seem to find any docs that lay it out clearly   It seems like it is expecting not only a declaration but also loading of the array to occur which is what I do not want but I also tried loading it with three elements but it still didn t work right  As I stated though I want to load it in the for loop  Any help will be appreciated   I did try to set the array size but got the same error  here is the exact code  maybe it is elsewhere  import android app Activity  import android os Bundle  import android view View  import android view View OnClickListener  import android widget Button  import android widget ListView   public class MainActivity extends Activity    ListView list  LazyAdapter adapter    Override public void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout main        list  ListView findViewById R id list       adapter new LazyAdapter this  mStrings       list setAdapter adapter        Button b  Button findViewById R id button1       b setOnClickListener listener       Override public void onDestroy         list setAdapter null       super onDestroy       public OnClickListener listener new OnClickListener         public void onClick View arg0            adapter imageLoader clearCache            adapter notifyDataSetChanged               private String   title              Abundance            Anxiety            Bruxism            Discipline            Drug Addiction      String urlbase    http   imobilize s3 amazonaws com giovannilordi data    String imgSel     logo png       String   mStrings   new String title length     ERROR SHOWS HERE  for int i 0 i lt title length i          mStrings i    urlbase   title i  replaceAll    a-zA-Z        toLowerCase     imgSel        source  imobilizeit com

You can write like below  Check out the syntax guidelines in this thread  AClass   array      array   new AClass   object1  object2     If you find arrays annoying better use ArrayList

You are not initializing your String    You either need to initialize it using the exact array size  as suggested by  Tr nSiLong  or use a List lt String gt  and then convert to a String    in case you do not know the length    String   title              Abundance            Anxiety            Bruxism            Discipline            Drug Addiction         String urlbase    http   www somewhere com data    String imgSel     logo png   List lt String gt  mStrings   new ArrayList lt String gt      for int i 0 i lt title length i          mStrings add urlbase   title i  toLowerCase     imgSel        System out println mStrings i       String   strings   new String mStrings size     strings   mStrings toArray strings    now strings is the resulting array

I think the beginning to the resolution to this issue is the fact that the use of the for loop or any other function or action can not be done in the class definition but needs to be included in a method constructor block definition inside of a class

As Tr n Si Long suggested  use   String   mStrings   new String title length     And replace string concatation with proper parenthesis   mStrings i     urlbase    title i  replaceAll    a-zA-Z          toLowerCase     imgSel    Try this  If it s problem due to concatation  it will be resolved with proper brackets  Hope it helps

Declare the array size will solve your problem   String   title                  Abundance                Anxiety                Bruxism                Discipline                Drug Addiction                 String urlbase    http   www somewhere com data        String imgSel     logo png       String   mStrings   new String title length        for int i 0 i lt title length i              mStrings i    urlbase   title i  toLowerCase     imgSel           System out println mStrings i
