Help with randomizing list

1

What would be the best way to randomize a custom course list I have created entered into a list box? The data is being added using :



// Adds 7 items, with data values, to the list
listBox.addItem("ID", "<b>title of class</b><br>Description of class.<i>credits</i>");
listBox.addItem("ID1", "<b>title of class</b><br>Description of class.<i>credits</i>"); 
listBox.addItem("ID2", "<b>title of class</b><br>Description of class.<i>credits</i>"); 
listBox.addItem("ID3", "<b>title of class</b><br>Description of class.<i>credits</i>"); 
listBox.addItem("ID4", "<b>title of class</b><br>Description of class.<i>credits</i>"); 
listBox.addItem("ID5", "<b>title of class</b><br>Description of class.<i>credits</i>"); 
listBox.addItem("ID6", "<b>title of class</b><br>Description of class.<i>credits</i>");
