    <blockquote> <p><strong>Possible Duplicate:</strong><br> <a href="https://stackoverflow.com/questions/1795402/java-check-a-string-if-there-is-a-special-character-in-it">JAVA: check a string if there is a special character in it</a> </p> </blockquote> <p>I am a novice programmer and am looking for help determining if a character is a special character. My program asks the user to input the name of a file, and the program reads the text in the file and determines how many blanks spaces, digits, letters, and special characters are in the text. I have the code completed to determine the blanks, digits, and letters, however am unsure of how to check if a character is a special character. Any help you can offer is appreciated and if something was not clear enough I can try to elaborate. My code so far is: </p> <pre><code>import java.util.Scanner; import java.io.*; public class TextFile{ public static void main(String[] args){ Scanner input = new Scanner (System.in); String fileName; boolean goodName = false; int blankCount = 0; int letterCount = 0; int digitCount = 0; int specialcharCount = 0; String currentLine; char c; Scanner lineFile= null; FileReader infile; System.out.println("Please enter the name of the file: "); fileName = input.nextLine(); while (!goodName) { try{ infile = new FileReader(fileName); lineFile = new Scanner(infile); goodName= true; } catch(IOException e) { System.out.println("Invalid file name, please enter correct file name: "); fileName=input.nextLine(); } } while (lineFile.hasNextLine()){ currentLine = lineFile.nextLine(); for(int j=0; j&lt;currentLine.length();j++){ c=currentLine.charAt(j); if(c== ' ') blankCount++; if(Character.isDigit(c)) digitCount++; if(Character.isLetter(c)) letterCount++; if() specialcharCount++; } } } } </code></pre> <p>I need something to put in the if statement at the end to increment specialcharCount. </p>

    2. CODepending on your definition of special character a simple `else specialCharCount++` would do it.

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.
