Creating JList Components

public JList() JList jlist = new JList(); public JList(Object listData[]) String labels[] = { "A", "B", "C", "D", "E", "F", "G", "H"}; JList jlist = new JList(labels); public JList(Vector listData) Vector vector = aBufferedImage.getSources(); JList jlist = new JList(vector); public JList(ListModel model) ResultSet results = aJDBCStatement.executeQuery("SELECT colName FROM tableName"); DefaultListModel model = new DefaultListModel(); while (result.next()){   model.addElement(result.getString(1)); }   JList jlist = new JList(model); To improve performance, you can set the fixedCellHeight and fixedCellWidth properties. Setting these properties is one way to avoid having the JList ask each cell for its rendered size.
