    <p>You have "switch(ch)" but you never assigned it a value. You declared it using "char ch;" but that's not enough.</p> <p>Maybe you want to do:</p> <pre><code>ch = phrase.charAt(i); </code></pre> <p>inside of your loop.</p> <p>So your combined code can look like this:</p> <pre><code>import java.util.Scanner; public class Count { public static void main (String[] args) { String phrase; // a string of characters int countBlank; // the number of blanks (spaces) in the phrase int length; // the length of the phrase char ch; // an individual character in the string int countA=0,countE=0,countS=0,countT=0; Scanner scan = new Scanner(System.in); // Print a program header System.out.println (); System.out.println ("Character Counter"); System.out.println (); // Read in a string and find its length System.out.print ("Enter a sentence or phrase: "); phrase = scan.nextLine(); length = phrase.length(); // Initialize counts countBlank = 0; // a for loop to go through the string character by character for (int i = 0; i &lt; phrase.length(); i++) { if(phrase.charAt(i) == ' ') countBlank++; ch = phrase.charAt(i); switch(ch) { case 'a': case 'A': countA++; break; case 'e': case 'E': countE++; break; case 's': case 'S': countS++; break; case 't': case 'T': countT++; break; } } // Print the results System.out.println (); System.out.println ("Number of blank spaces: " + countBlank); System.out.println ("Number of a: " + countA); System.out.println ("Number of e: " + countE); System.out.println ("Number of s: " + countS); System.out.println ("Number of t: " + countT); System.out.println (); } } </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
