You can use JList’s default cell renderer to display icons, as
shown in Figure 39.22(b), using the following code:
ImageIcon denmarkIcon = new ImageIcon(getClass().getResource(
"image/denmarkIcon.gif"));
...
JList list = new JList(new ImageIcon[]{denmarkIcon, germanyIcon,
chinaIcon, indiaIcon, norwayIcon, ukIcon, usIcon});
How do you display a string along with an icon in one cell, as
shown in Figure 39.22(c)? You need to create a custom renderer by
implementing ListCellRenderer, as shown in Figure 39.23.

ListCellRenderer defines how cells are rendered in a list.
Suppose a list is created as follows:
JList list = new JList(new Object[][]{{denmarkIcon, "Denmark"},
{germanyIcon, "Germany"}, {chinaIcon, "China"},
{indiaIcon, "India"}, {norwayIcon, "Norway"}, {ukIcon, "UK"},
{usIcon, "US"}});
Each item in the list is an array that consists of an icon and a
string. You can create a custom cell renderer that retrieves an
icon and a string from the list data model and display them in a
label. The custom cell renderer class is given in Listing 39.9.
