在 Java 中在控制台上显示 JTabbedPane 选项卡的所有标题
java 8object oriented programmingprogramming
要显示 JTabbedPane 的所有标题，我们首先获取选项卡的数量 −
int count = tabbedPane.getTabCount();
现在，循环遍历 JTabbedPane 中的选项卡数量。使用 getTitleAt() 获取每个选项卡的标题 −
for (int i = 0; i < count; i++) {
String str = tabbedPane.getTitleAt(i);
System.out.println(str);
}
以下是在控制台上显示 JTabbedPane 选项卡的所有标题的示例 −
示例
package my;
import javax.swing.*;
import java.awt.*;
public class SwingDemo {
public static void main(String args[]) {
JFrame frame = new JFrame("Devices");
JTabbedPane tabbedPane = new JTabbedPane();
JTextArea text = new JTextArea(100,100);
JPanel panel1, panel2, panel3, panel4, panel5, panel6, panel7, panel8;
panel1 = new JPanel();
panel2 = new JPanel();
panel2.add(text);
panel3 = new JPanel();
panel4 = new JPanel();
panel5 = new JPanel();
panel6 = new JPanel();
panel7 = new JPanel();
panel8 = new JPanel();
tabbedPane.setBackground(Color.blue);
tabbedPane.setForeground(Color.white);
tabbedPane.addTab("Laptop", panel1);
tabbedPane.addTab("Desktop ", panel2);
tabbedPane.addTab("Notebook", panel3);
tabbedPane.addTab("Echo ", panel4);
tabbedPane.addTab("Tablet", panel5);
tabbedPane.addTab("Alexa ", panel6);
tabbedPane.addTab("Notebook", panel7);
tabbedPane.addTab("iPad", panel8);
int count = tabbedPane.getTabCount();
for (int i = 0; i < count; i++) {
String str = tabbedPane.getTitleAt(i);
System.out.println(str);
}
frame.add(tabbedPane);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(600,350);
frame.setVisible(true);
}
}
运行时，控制台将显示所有选项卡的值 −
