完成此任务的最佳布局管理器
我有（2）JTextAreas（输入文本和输出文本）
（2）JComboBoxes（AutoDetect＆amp; TranslateTo）
请参阅附图，了解目标是什么。
我正在尝试使用某个布局管理器获取此布局我已经尝试过FlowLayout，SpringLayout并且没有用这些获得理想的结果。这是我的代码
public class translate extends JFrame implements ActionListener{
/*
Our Langauges of choice we can add more if desired in the future
*/
String[] nativeString = { "Auto-Detect"};
String[] translateString = { "Español", "中文", "Francais", "Italiano", "Deutsche" , "English" };
JComboBox nativeLanguage;
JComboBox translateTo;
JButton execute;
final JPanel topRight;
final JPanel topLeft;
final JPanel bottomLeft;
JPanel bottomRight;
JLabel tR;
JLabel tL;
JLabel bR;
JLabel bL;
JRadioButton local;
JRadioButton mainArea;
JTextArea input;
JTextArea output;
public translate() throws Exception{
super("Translation Service");
JOptionPane.showMessageDialog(null, "Translation Services Require A NetWork Function To Make Calls");
Translate.setClientId("xxxxxxxxx");
Translate.setClientSecret("Xxxxxxxxxxxx);
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setSize(700,400);
setLocationRelativeTo(null);
setResizable(true);
setLookAndFeel();
SpringLayout spring = new SpringLayout();
setLayout(spring);
input= new JTextArea();
JScrollPane inScroll = new JScrollPane();
input.add(inScroll);
input.setEditable(true);
input.setLineWrap(true);
execute = new JButton("Translate");
execute.addActionListener(this);
output = new JTextArea();
JScrollPane outScroll = new JScrollPane();
output.add(outScroll);
output.setEditable(true);
output.setLineWrap(true);
output.setVisible(true);
/*
Our JComboBoxes for user to selct langauge they want to choose
*/
nativeLanguage = new JComboBox(nativeString);
translateTo = new JComboBox(translateString);
nativeLanguage.addActionListener(this);
translateTo.addActionListener(this);
// JLabels
tR = new JLabel("Auto-Detect");
tL = new JLabel ("Target Langauge");
// FlowLayout fl = new FlowLayout();
SpringLayout sp = new SpringLayout();
setLayout(sp);
// setLayout(fl);
//1
topRight = new JPanel();
// topRight.setLayout(new BoxLayout(topRight, BoxLayout.PAGE_AXIS));
topRight.add(nativeLanguage);
topRight.add(tR);
//2
topLeft = new JPanel();
// topLeft.setLayout(new BoxLayout(topLeft, BoxLayout.PAGE_AXIS));
topLeft.add(translateTo);
topLeft.add(tL);
//3
bottomRight = new JPanel();
// bottomRight.setLayout(new BoxLayout(bottomRight, BoxLayout.PAGE_AXIS));
bottomRight.add(input);
//4
bottomLeft = new JPanel();
// bottomLeft.setLayout(new BoxLayout(bottomLeft, BoxLayout.LINE_AXIS));
bottomLeft.add(output);
add(topRight, SpringLayout.NORTH);
add(topLeft, SpringLayout.NORTH);
add(bottomRight, SpringLayout.SOUTH);
add(bottomLeft, SpringLayout.SOUTH);
setVisible(true);
}

我认为GridLayout适合你。如果您想要更灵活，也可以使用GridBagLayout。 Here是指向所有布局管理器和关联示例的链接。
但是你真的想用摇摆吗？看来你刚开始使用项目的GUI部分，所以也许你应该考虑使用javafx而不是swing。
