性别单选按键组的问题，你性别单选按钮组是用的JPanel装的两个JRadioButton吧，把这个JPanel的Layout设为 new FlowLayout(FlowLayout.CENTER, 0, 0)就OK了，见下面代码：
Java代码
package org.zergle.test.swing;

import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JTextField;
import javax.swing.border.LineBorder;
public class ReaderAddIFrame extends JFrame {
private JLabel lblName = new JLabel("姓名");
private JTextField txtName = new JTextField();
private JLabel lblSex = new JLabel("性别");
private JRadioButton radMale = new JRadioButton("男");
private JRadioButton radFemale = new JRadioButton("女");
private JLabel lblAge = new JLabel("年龄");
private JTextField txtAge = new JTextField();
private JLabel lblCareer = new JLabel("职业");
private JTextField txtCareer = new JTextField();
private JPanel pnl1 = new JPanel();
private JPanel pnl1_1 = new JPanel(new GridLayout(2, 4));
private JPanel pnlSexGroup = new JPanel(new FlowLayout(FlowLayout.CENTER, 0, 0));
public ReaderAddIFrame() {
this.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
this.pnlSexGroup.add(this.radMale);
this.pnlSexGroup.add(this.radFemale);
this.pnl1_1.add(this.lblName);
this.pnl1_1.add(this.txtName);
this.pnl1_1.add(this.lblSex);

this.pnl1_1.add(this.txtCareer);
this.pnl1.add(this.pnl1_1);
this.add(this.pnl1, BorderLayout.CENTER);
this.setSize(600, 400);
this.setVisible(true);
}
public static void main(String[] args) {
new ReaderAddIFrame();
}
}
