To make multiple list selections, you can use the anchor and lead indices of the selection items

void setAnchorSelectionIndex( int index)      void setLeadSelectionIndex(int index) import java.awt.BorderLayout; import javax.swing.JFrame; import javax.swing.JList; import javax.swing.JScrollPane; public class JListSelectionModeAnchor {   static String labels[] = { "A", "B", "C", "D", "E", "F", "G" };   public static void main(String args[]) {     JFrame frame = new JFrame("Modifying Model");     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     JList jlist = new JList(new String[]{"A","B","C"});          jlist.getSelectionModel().setAnchorSelectionIndex(0);        jlist.getSelectionModel().setLeadSelectionIndex(2);          JScrollPane scrollPane1 = new JScrollPane(jlist);     frame.add(scrollPane1, BorderLayout.CENTER);     frame.setSize(640, 300);     frame.setVisible(true);   } }
