문제 설명
특정 형식의 JAVA GUI 제작에 대한 질문 (Question about making a JAVA GUI of a certain format)
다음과 같은 GUI를 만들려고 합니다. 
저는 5개의 버튼을 위한 공간이 있는 BorderLayout을 사용하는 방법만 알고 있습니다. 북쪽, 서쪽, 중앙, 동쪽 및 남쪽입니다.
최상단에 6개의 구성 요소가 있어야 하므로 이 접근 방식은 작동하지 않습니다. 맨 윗줄에 둘 이상의 구성 요소를 가질 수 있도록 만드는 방법을 모르겠습니다. 사용할 수 있는 다른 레이아웃이 있습니까? 아니면 BorderLayout을 조작하여 맨 윗줄에 6개의 구성 요소를 배치할 수 있습니까?

방법 1:
What you need to do is nest components inside of other components. For example, the top (North) should be one JPanel. That JPanel will contain the 6 components on the top.
The code may look similar to the following:
JPanel northPane = new JPanel();
northPane.add(new JLabel("Principle: "));
northPane.add(principleTextBox);
... and so on
mainPanel.setLayout(new BorderLayout());
mainPanel.add(northPanel, BorderLayout.NORTH);
The Center component will probably be another JPanel containing the two center buttons. And the South component will be another JPanel containing the single JLabel or simply the JLabel.
If you don't have to use a BorderLayout for the main panel, it may be easier to use a BoxLayout.
방법 2:
Once again I turn to miglayout, the absolute best layout manager for Java. No nested JPanels, just a simple layout using string based constraints.
With debug mode on: 
After resizing the window (note the ratio of the size of the textfields remains the same) 
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import net.miginfocom.swing.MigLayout;
/**

public class InterestCalculator extends JPanel {
public InterestCalculator() {
super(new MigLayout("debug, fill", "align center"));
// Make 6 components cram into one cell
add(new JLabel("Principal:"), "split 6");
// This textfield grows at twice the normal rate
add(new JTextField(), "growx 200");
add(new JLabel("Interest rate (percentage):"));
// This one at a normal rate
add(new JTextField(), "growx 100");
add(new JLabel("Years:"));
// This one at half the normal rate
add(new JTextField(), "growx 50, wrap");
// The row with the two buttons
add(new JButton("Compute simple interest"), "split 2");
add(new JButton("Compute compound interest"), "wrap");
// The result label
add(new JLabel("The result with simple interest would be"));
}
public static void main(String[] args) {
JFrame frame = new JFrame("");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new InterestCalculator();
frame.add(panel);
frame.pack();
frame.setVisible(true);
}
}

If I were recreating that UI, I would start with a JPanel using a GridLayout with 3 rows and 1 column. In each column I would add a child JPanel.
Then for each row I would use a GridBagLayout to position the components.

Here is a tutorial about layout managers.
Remember that you can always add several elements to a JPanel and apply a specific layout to that JPanel. Then you can nest panels(add panels inside other panels).
