Fetching Table Names from Oracle with Java?

Question

I'm working on a Java GUI project; in one of its property screen I use 3 comboboxes in order to get: first user chooses DB name, with this value 2.Schema names and with this all table names under that schema. It's OK when I use ResultSet when getting the values from DB and setting them. But with this way, I could only bring ONE value because you know the way ResultSet works. So is there any other way that I could fetch all the table names with let's say:

SELECT TABLE_NAME FROM ALL_TABLES; and put them on an array of Strings or sth... Anything possible, I just wanna have their names in a list or anything.

Thank you.

EDIT:

Here's the simple code tested for the purpose:

ResultSet rs = null;
PreparedStatement ps = null;
String result;
ps = conn.prepareStatement("SELECT TABLE_NAME FROM ALL_TABLES");

rs = ps.executeQuery(); 

while(rs.next())
{
        result = rs.getString(1);
    System.out.println(rs.getString(1));
}

You could also use:

DatabaseMetaData  metadata = currentConnection.getMetaData();
String[] names = {"TABLE"}; 
ResultSet tables = metadata.getTables(null,"%", "%", names);
while (tables.next()) { 
  String tableName = tables.getString("TABLE_NAME"); 
  String tableSchema = tables.getString("TABLE_SCHEM");
}

You need to quesry for meta data basically. See this example on how to do it.

Answer 3

Not sure what you mean by 'you know the way resultset works'?! This will return all the rows from the query:

while (rs.next()) {
    System.out.print("Column 1 returned ");
    System.out.println(rs.getString(1));
}

Answer 4

Just use a List:

List<String> tableNames = new ArrayList<String>();
while(rs.next()) {
    String tableName = rs.getString(1);
    tableNames.add(tableName);
}
// there: your list contains all the table names
