1. SpringLayout allows you to attach "springs" to components.
2. Components are laid out relative to other components.
3. Each component added to the container can have an attached SpringLayout.Constraints.

import java.awt.Component;
import java.awt.Container;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;
import javax.swing.SpringLayout;

public class SpringSample {
  public static void main(String args[]) {
    JFrame frame = new JFrame("SpringLayout");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    Container contentPane = frame.getContentPane();

    SpringLayout layout = new SpringLayout();
    contentPane.setLayout(layout);

    Component left = new JLabel("Left");
    Component right = new JTextField(15);

    contentPane.add(left);
    contentPane.add(right);
    layout.putConstraint(SpringLayout.WEST, left, 10, SpringLayout.WEST, contentPane);
    layout.putConstraint(SpringLayout.NORTH, left, 25, SpringLayout.NORTH, contentPane);
    layout.putConstraint(SpringLayout.NORTH, right, 25, SpringLayout.NORTH, contentPane);
    layout.putConstraint(SpringLayout.WEST, right, 20, SpringLayout.EAST, left);

    frame.setSize(300, 100);
    frame.setVisible(true);
  }
