如何在 Java 中向 JTabbedPane 中新增選項卡？

我們首先建立一個 JTabbedPane −

JTabbedPane tabbedPane = new JTabbedPane();

建立一些面板 −

JPanel panel1, panel2, panel3, panel4, panel5;
panel1 = new JPanel();
panel2 = new JPanel();
panel3 = new JPanel();
panel4 = new JPanel();
panel5 = new JPanel();

現在，使用 addTab() 方法新增選項卡並將面板也設定為選項卡將在其中可見 −

tabbedPane.addTab("PHP", panel1);
tabbedPane.addTab("Blockchain ", panel2);
tabbedPane.addTab("Matlab", panel3);
tabbedPane.addTab("JSP ", panel4);
tabbedPane.addTab("Servlet", panel5);

以下示例展示瞭如何在 JTabbedPane 中新增選項卡 −

package my;
import javax.swing.*;
import java.awt.*;
public class SwingDemo {
   public static void main(String args[]) {
      JFrame frame = new JFrame("Technologies");
      JTabbedPane tabbedPane = new JTabbedPane();
      JPanel panel1, panel2, panel3, panel4, panel5;
      panel1 = new JPanel();
      panel2 = new JPanel();
      panel3 = new JPanel();
      panel4 = new JPanel();
      panel5 = new JPanel();
      tabbedPane.addTab("PHP", panel1);
      tabbedPane.addTab("Blockchain ", panel2);
      tabbedPane.addTab("Matlab", panel3);
      tabbedPane.addTab("JSP ", panel4);
      tabbedPane.addTab("Servlet", panel5);
      frame.add(tabbedPane);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.setSize(550,350);
      frame.setVisible(true);
   }
}
