要创建空边框，请使用 createEmptyBorder() 方法。让我们首先创建一个标签组件 −
JLabel label = new JLabel("Label with empty border!");
现在，使用 BorderFactory 类创建空边框 −
label.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
以下是创建空边框的示例 −
示例
package my;
import javax.swing.BorderFactory;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class SwingDemo {
public static void main(String[] args) throws Exception {
JFrame frame = new JFrame("Demo");
JLabel label;
label = new JLabel("Label with empty border!");
label.setFont(new Font("Verdana", Font.PLAIN, 16));
label.setVerticalAlignment(JLabel.BOTTOM);
label.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
frame.add(label);
frame.setSize(550,350);
frame.setVisible(true);
}
}
输出
