    <p>I have just made a program that is supposed to scan a file and count the number of lines, vowels, and many other things but when I run it, it goes into an infinite loop. I'm pretty sure it has to do with the <code>.hasNext()</code> and <code>.hasNextLine()</code> methods which I am not very familiar with</p> <pre><code>import java.util.*; import java.io.*; /** * * */ public class Wordcount1 { public static void main(String[] args) { int vowels=0; int punctuation=0; int sentences=0; int words=0; int lines=0; int alphaNumeric=0; try{ Scanner input = new Scanner(System.in); System.out.println("Enter file name: "); File file = new File(input.nextLine()); Scanner fileReader = new Scanner(file); while(fileReader.hasNextLine()){ lines +=1; } while(fileReader.hasNext()){ { fileReader.next(); words +=1; } String word = fileReader.next(); for (int i=0; i&lt;word.length();i++){ char ch= word.charAt(i); if(ch=='a'||ch=='e'||ch=='i'||ch=='o'||ch=='u') vowels +=1; if((ch=='!'||ch=='.'||ch=='?')) sentences +=1; if(Character.isLetterOrDigit(ch)) alphaNumeric +=1; switch(ch){ case ',': punctuation +=1; break; case '[': punctuation +=1; break; case ']': punctuation +=1; break; case ':': punctuation +=1; break; case '`': punctuation +=1; break; case '-': punctuation +=1; break; case '!': punctuation +=1; break; case '_': punctuation +=1; break; case '(': punctuation +=1; break; case ')': punctuation +=1; break; case '.': punctuation +=1; break; case '?': punctuation +=1; break; case '"': punctuation +=1; break; case ';': punctuation +=1; break; } } } System.out.println("The number of words in the file name: " + words); System.out.println("The number of lines in the file name: " + lines); System.out.println("The number of alphanumeric characters: " + "in the file name: " + alphaNumeric); System.out.println("The number of sentences in the file name: " + sentences); System.out.println("The number of vowels in the file name: " + vowels); System.out.println("The number of punctuations in the file name: " + punctuation); }catch(FileNotFoundException e){ e.printStackTrace(); } } } </code></pre>

    1. COIn your first cycle to count the lines you never read actually read anything and the pointer to the file remains in the same place.

    2. COYou program needs a lot of work (too much to cover), but you might consider this small cleanup: replace `words +=1` with `words++` (etc)

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.
