    <p>Ok, so I really didn't know how to say it right for the title so this should shed some light on the situation.</p> <p>I'm making a palindrome program in Java. In every which way you look at it, it works just fine. It reads in a file using <code>Scanner</code>, searches through the entire file and outputs if that line in the text file is a palindrome. If you have any special characters or caps it deletes them and turns everything to lowercase.</p> <p>My issue is that after the check is done on each line, I want to show some extra information next to the result.</p> <p>Each line should show how many words are in the line, how many characters and if its a palindrome or not.</p> <p>Anyway here is the code, hopefully someone can help me figure this out. Thanks.</p> <pre><code>import java.io.File; import java.util.Scanner; public class Palindrome { public static void main(String[] args) { //Global Variables Scanner cScan = null; Scanner wScan = null; Scanner pScan = null; int charCount = 0, numLines = 0, numChars = 0, wordCount = 0; //Take in User Input Scanner iScan = new Scanner(System.in); //Start input Scanner String fileName = null; System.out.print("Please Enter a File Name: "); fileName = iScan.nextLine(); iScan.close(); //Close input Scanner //Read File Specified by User File palin = new File(fileName); try { //Checks for Number of Characters cScan = new Scanner(palin); while(cScan.hasNextLine()) { String line = cScan.nextLine(); numChars += line.length(); numLines++; } //Checks for Number of Words wScan = new Scanner(palin); while (wScan.hasNext()) { wScan.next(); wordCount++; } //Format Lines pScan = new Scanner(palin); while (pScan.hasNext()) { String line = pScan.nextLine(); String reString = line.replaceAll("[^\\p{L}\\p{Nd}]", ""); String lString = reString.toLowerCase(); boolean pali = false; String tP = "Yes", fP = "No"; int n = lString.length(); for (int i = 0; i &lt; (n / 2) + 1; ++i) { if (lString.charAt(i) != lString.charAt(n - i - 1)) { pali = false; break; } else if (lString.charAt(i) == lString.charAt(n - i - 1)) { pali = true; break; } } if (pali == true) System.out.println(line + " w: " + wordCount + ", " + " c: " + charCount + ", " + tP); else System.out.println(line + " w: " + wordCount + ", " + " c: " + charCount + ", " + fP); } } catch(Exception e) { System.out.println("File Could Not be Found"); } //charCount = (numLines + numChars) - 1; //Minus 1 to Compensate for EOL at EOF //System.out.println(charCount); //System.out.println(wordCount); //System.out.println(spRemover); } } </code></pre>

    3. COIn case you don't know: There is `System.out.print()` method that continues output to the current line (does not start with the new line). So you can use this method instead of concatenating the entire line before printing.

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.
