Body
There are three ways to approach this problem: <ul> <li>Call <code>next()</code> on the Scanner, and extract the first character of the String (e.g. <code>charAt(0)</code>) If you want to read the rest of the line as characters, iterate over the remaining characters in the String. Other answers have this code.</li> <li>Use <code>setDelimiter("")</code> to set the delimiter to an empty string. This will cause <code>next()</code> to tokenize into strings that are exactly one character long. So then you can repeatedly call <code>next().charAt(0)</code> to iterate the characters. You can then set the delimiter to its original value and resume scanning in the normal way!</li> <li>Use the Reader API instead of the Scanner API. The <code>Reader.read()</code> method delivers a single character read from the input stream. For example: <pre><code>Reader reader = new InputStreamReader(System.in); int ch = reader.read(); if (ch != -1) { // check for EOF // we have a character ... } </code></pre></li> </ul> <hr> When you read from the console via <code>System.in</code>, the input is typically buffered by the operating system, and only "released" to the application when the user types ENTER. So if you intend your application to respond to individual keyboard strokes, this is not going to work. You would need to do some OS-specific native code stuff to turn off or work around line-buffering for console at the OS level.

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.
