我想在JLabel(s)之间创建空间，并将JButtons对齐到同一行

Question

我使用不同的布局在Java中创建了一个注册页面，我在同一行上对齐按钮并在每个JLabel之间创建空间时遇到了麻烦。你可以在链接(https://postimg.org/image/jaur8rxz7/)上看到它。这是我写的代码

package liblog;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Aregistration extends JFrame {
 private JTextField text;
 private JTextField text2;
 private JPasswordField pass;
 private JButton log1;
 private JButton sign1;
 JFrame frame = new JFrame();
 JPanel panel = new JPanel(new GridBagLayout());
 JLabel label1 = new JLabel();
 JLabel label3 = new JLabel();
 JLabel label2 = new JLabel();
 Aregistration(){
     super("Admin Registration");
     setLayout(new FlowLayout(FlowLayout.CENTER,15,15));
     setBounds(500,500,500,250);
     setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     Container con = this.getContentPane();
     con.add(panel);
     panel.setLayout(new BoxLayout(panel,BoxLayout.Y_AXIS));

     label1=new JLabel("First Name");
     label1.setToolTipText("Enter Your First Name");
     text = new JTextField("Name",20);
     label2=new JLabel("Registration No");
     label2.setToolTipText("Enter Your Registation no");
     text2 = new JTextField("Registation No",20);

     label3 = new JLabel("Password");
     label3.setToolTipText("Enter Your Password");
     pass = new JPasswordField("Password",20);

     log1 = new JButton("Log In");
     sign1 = new JButton("Register");

     panel.add(Box.createRigidArea(new Dimension(0, 0)));
     panel.add(Box.createVerticalStrut(HEIGHT));
     panel.add(label1);
     panel.add(text);
     panel.add(label2);
     panel.add(text2);
     panel.add(label3);
     panel.add(pass);

    panel.add(log1);
    panel.add(sign1);

     setVisible(true);
 }
 public static void main(String[]args){new Aregistration();
 }
}

我在对齐同一行的按钮时遇到了麻烦

创建第二个面板并将按钮添加到面板中，然后将该面板添加到主面板中:

JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(new BoxLayout(buttonPanel,BoxLayout.X_AXIS));
buttonPanel.add( log1 );
buttonPanel.add( Box.createHorizontalStrut(5) );
buttonPanel.add( sign1 );
panel.add( buttonPanel );

并在每个JLabel

之间创建空间

您也可以使用垂直支柱。

请阅读Swing教程中关于如何使用BoxLayout的部分，了解更多信息和示例。
