    <p>I'm trying to read a word and its corresponding code from a file for a project. This is the code I have, and it reads it fine, just for some reason spaces are added after some, but not all, of the codes. I do not understand why it is happening. </p> <p>The code is:</p> <pre><code>public void loadDictionary(String file){ String fileName=file; String fileNameTwo=file; //Coder c=new Coder(); String string; String code; String s=null; try{//System.out.println("1"); FileReader freader=new FileReader(fileName); FileReader freaderTwo=new FileReader(fileNameTwo); //System.out.println("1"); BufferedReader inFile=new BufferedReader(freader); BufferedReader inFileTwo=new BufferedReader(freaderTwo); //System.out.println("2"); //System.out.println("3"); if ((s=inFile.readLine())==null){ System.out.println("5"); throw new EmptyFileException("Nothing in file to upload."); } while ((s=inFileTwo.readLine())!=null){ //System.out.println("4"); //System.out.println(s); String[] tokens=s.split(" "); string=tokens[0]; //System.out.println(string); code=tokens[1]; //System.out.println(code); this.insert(string, code); System.out.println(code+"."); }//end while //this.printCoder(); }//end try catch(EmptyFileException ex){ } catch(IOException ex){ System.out.println("Error in uploading dictionary."); } }//end method </code></pre> <p>...and the output is (of the codes):</p> <pre><code> 5721. 9963. 4432 . 1143 . 6402 . 3333 . 4924 . 1429 . 3110 . 3036 . 2736 . 8064. </code></pre> <p>The periods are there to show how many spaces are added in. I just appended a period in the system.out.println().</p> <p>Edit: The periods aren't coming out quite right....but you get the idea. The are really sometimes more/less spaces than it is showing.</p>

    1. COAre you sure they are spaces? Since you are splitting accorsing to spaces, more likely these are tabs. retry splitting with: `String[] tokens=s.split("\\s+");` and tell me if it solves it or changes anything in the output.

    2. COCheck your data. `readLine()` doesn't add spaces, or anything else. The only thing it does to the data is to *remove* newlines.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
