Parsing Strings Delimited by Double Spaces in a Database Field
From a single field of a database, I need to read and parse multiple strings delimited by 2 spaces. Each possible entry from this field is represented in a JList, so I'm wanting the JList entries that are present in the database field to be highlighted. An example entry in the database might be:
This is string1this is string2this is string3
So I'd want three different selections highlighted in my JList: "This is string1" "this is string2" and "this is string3"
Can anyone suggest a good way to do this? I've been playing around with the Reader class and Scanner class, but can't seem to get the working logic down on paper. Thanks for the help!

I think this is working and I now have a String[] of values to work with. What I'm needing to do now is to highlight each value from the String[] on a pre-populated JList. I tried JList.setSelectedIndex(), but that won't work with multiple strings. Any ideas? Below is what I tried:
String[] classes = MainMenu.rs.getString(6).trim().split(" ");
for(int i = 0; i < classes.length; i++)
{
jList1.setSelectedValue((Object)classes[i]);
}
Only the last element of the array is getting highlighted. I checked the contents of the array, and there are multiple entries. How can I get all of the entries highlighted?

Probably too late but can help to someone else. This should do the job:
String[] classes = MainMenu.rs.getString(6).trim().split(" ");
int[] indices = new int[classes.length];
for (int i = 0; i < classes.length; i++) {
indices[i] = i;
}
jList1.setListData(classes);
jList1.setSelectedIndices(indices);
