java swing 如何控制组件的想要位置

我做的这个是这样的 人家是这样的 我想弄人家那样的

试了试弄不好 不会啊

      JPanel panel = new JPanel();      
      panel.add(你的文字对应的Label名);
      panel.add(你的文本框对应的Textfield名);
      panel.setAlignmentX(Component.LEFT_ALIGNMENT);   
      GridBagConstraints gbc = new GridBagConstraints();
      gbc.gridy = sliderPanel.getComponentCount();    //gridx/gridy：组件的横纵坐标
      gbc.anchor = GridBagConstraints.WEST;     
      //当组件不能填满其格时，通过 anchor来设置组件的位置，anchor有两种值，绝对和相对的值分别有 若干个
      你的能大panel.add(panel, gbc);    

这个是我做的滑动条的部分代码，你用的话要改。

可以采取空布局的方式控制具体的位置：
frame.setLayout(null);
frame.add(button1);
button1.setBounds(100,50,80,30);//修改控件位置和大小信息

你可以试试。

private JPanel getInfoPane() {

    JPanel infoPane = new JPanel();
    infoPane.setBorder(BorderFactory.createTitledBorder(""));

    定义相关的标签和文本框，运行后是这样的
