Java/Swing JFC/Alignment

Laying Out a Screen with Different Component Alignments

import java.awt.ruponent;
import javax.swing.BoxLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class AlignY {
  public static void main(String args[]) {
    JFrame frame = new JFrame("Y Alignment");
    JPanel contentPane = (JPanel) frame.getContentPane();
    BoxLayout layout = new BoxLayout(contentPane, BoxLayout.X_AXIS);
    contentPane.setLayout(layout);
    JButton button = new JButton("0.0");
    button.setAlignmentY(Component.TOP_ALIGNMENT);
    contentPane.add(button);
    button = new JButton("1.0");
    button.setAlignmentY(Component.BOTTOM_ALIGNMENT);
    contentPane.add(button);
    button = new JButton("0.5");
    button.setAlignmentY(Component.CENTER_ALIGNMENT);
    contentPane.add(button);
    frame.setSize(200, 100);
    frame.show();
  }
}

Working with Component Alignments

import java.awt.ruponent;
import java.awt.Container;
import java.awt.FlowLayout;
import javax.swing.BoxLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class AlignX {
  private static Container makeIt(String labelChar, float alignment) {
    JPanel container = new JPanel();
    BoxLayout layout = new BoxLayout(container, BoxLayout.Y_AXIS);
    container.setLayout(layout);
    for (int i = 1; i < 6; i++) {
      String label = makeLabel(labelChar, i * 2);
      JButton button = new JButton(label);
      button.setAlignmentX(alignment);
      container.add(button);
    }
    return container;
  }
  private static String makeLabel(String s, int length) {
    StringBuffer buff = new StringBuffer(length);
    for (int i = 0; i < length; i++) {
      buff.append(s);
    }
    return buff.toString();
  }
  public static void main(String args[]) {
    JFrame frame = new JFrame("X Alignment");
    Container contentPane = frame.getContentPane();
    Container panel1 = makeIt("R", Component.RIGHT_ALIGNMENT);
    Container panel2 = makeIt("C", Component.CENTER_ALIGNMENT);
    Container panel3 = makeIt("L", Component.LEFT_ALIGNMENT);
    contentPane.setLayout(new FlowLayout());
    contentPane.add(panel1);
    contentPane.add(panel2);
    contentPane.add(panel3);
    frame.pack();
    frame.show();
  }
