Java Program to select all the items in a JList
To select all the items in a JList, use setSelectionInterval() and set a range:
JList list = new JList(sports);
int begn = 0;
int end = list.getModel().getSize() - 1;
if (end >= 0) {
list.setSelectionInterval(begn, end);
}The following is an example to select all the items in a JList:
Example
package my;
import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
class SwingDemo extends JFrame {
static JFrame frame;
static JList list;
public static void main(String[] args) {
frame = new JFrame("JList Demo");
SwingDemo s = new SwingDemo();
JPanel panel = new JPanel();
String sports[]= {"Football","Fencing","Cricket","Squash","Hockey","Rugby"};
list = new JList(sports);
int begn = 0;
int end = list.getModel().getSize() - 1;
if (end >= 0) {
list.setSelectionInterval(begn, end);
}
panel.add(list);
frame.add(panel);
frame.setSize(550,300);
frame.setVisible(true);
}
}Output
