Legal Studies如何在 Java JList 中儲存字串陣列？
要將字串陣列儲存在 JList 中，首先建立 String 陣列列表
String sports[]= { "Football","Fencing","Cricket","Squash","Hockey","Rugby"};現在，將其設定為 JList
JList list = new JList(sports);
以下是將在 JList 中儲存字串陣列的一個示例
示例
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);
}
}輸出
