    <p><em>What is the correct syntax for searching an <code>ArrayList</code> of strings for a single character? I want to check each string in the array for a single character. Ultimately I want to perform multiple search and replaces on all strings in an array based on the presence of a single character in the string. I have reviewed java-examples.com and java docs as well as several methods of searching ArrayLists. None of them do quite what I need. P.S. Any pointers on using some sort of file library to perform multiple search and replaces would be great.</em></p> <p><strong>--- Edit ---</strong></p> <p>As per MightyPork's recommendations <code>arraylist</code> revised to use simple <code>string</code> type. This also made it compatible with hoosssein's solution which is included.</p> <hr> <pre><code> public void ArrayInput() { String FileName; // set file variable FileName = fileName.getText(); // get file name ArrayList&lt;String&gt; fileContents = new ArrayList&lt;String&gt;(); // create arraylist try { BufferedReader reader = new BufferedReader(new FileReader(FileName)); // create reader String line = null; while ((line = reader.readLine()) != null) { if(line.length() &gt; 0){ // don't include blank lines line = line.trim(); // remove whitespaces fileContents.add(line); // add to array } } for (String row : fileContents) { System.out.println(row); // print array to cmd } String oldstr; String newstr; oldstr = "}"; newstr = "!!!!!"; for(int i=0;i&lt;fileContents.size();i++){ if(fileContents.contains(oldstr)){ fileContents.set(i, fileContents.get(i).replace(oldstr, newstr)); } } for (String row : fileContents) { System.out.println(row); // print array to cmd } // close file } catch (IOException ex) { // E.H. for try JOptionPane.showMessageDialog(null, "File not found. Check name and directory."); } } </code></pre>

    1. COYou would need to iterate over the list manually, and perform the search and replace.

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.
