Creating multiple images using a loop.

[John Wayne]

How? I've tried many times, this is what I have so far:

public static void addComponentsToPane(Container pane) {
for(int i = 0; i < 400; i++) {
pane.setLayout(null);
Insets insets = pane.getInsets();
ImageIcon icon = new ImageIcon("Grass.gif");
JLabel GrassTop = new JLabel(icon);
JLabel GrassBottom = new JLabel(icon);
Dimension sizeTop = GrassTop.getPreferredSize();
Dimension sizeBottom = GrassBottom.getPreferredSize();
GrassTop.setBounds(insets.left, insets.top, sizeTop.width, sizeTop.height);
GrassBottom.setBounds(insets.left - 20, insets.top + 20, sizeBottom.width - 20, sizeBottom.height);
pane.add(GrassTop);
pane.add(GrassBottom);
    }
}

But, I want to display the images within a certain amount of pixels so they don't overlap, help?

Welcome to the Java Ranch,

You could use a GridBagLayout and a GridBagConstraints object instead of using a null layout manager.

package com.kaydell.test;
 
import java.awt.Container;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.SwingUtilities;
 
// This annotation suppresses warnings about serialization for the following class.
@SuppressWarnings("serial")
 
// The grass window extends JFrame window and implements the Runnable interface to allow the window to be more thread-safe.
public class GrassWindow extends JFrame implements Runnable {

// This GridBagConstrainst object lets you control the size and placement of Component objects
public GridBagConstraints createGridBagConstrains() {
GridBagConstraints constraints = new GridBagConstraints();
constraints.anchor = GridBagConstraints.NORTH;
constraints.gridx = 0;
constraints.gridy = 0;
constraints.gridwidth = 1;
constraints.gridheight = 1;
return constraints;
}
 
// This method adds icons by row and column using the GridBagLayout and the GridBagConstraint objects.
public void addComponentsToPane() {
Container pane = getContentPane();
pane.setLayout(new GridBagLayout());
GridBagConstraints constraints = createGridBagConstrains();
ImageIcon icon = new ImageIcon("Grass.gif");
for(int i = 0; i < 20; i++) {
for (int j = 0; j < 20; j++) {
JLabel GrassTop = new JLabel(icon);
JLabel GrassBottom = new JLabel(icon);
constraints.gridx = i;
constraints.gridy = j;
pane.add(GrassTop,constraints);
pane.add(GrassBottom,constraints);
}
}
}

// This is called by the Swing thread to run this window on the Swing thread.
public void run() {
pack();
setVisible(true);
}

// Entry-point into the program.
public static void main(String[] args) {
GrassWindow theGrassWindow = new GrassWindow();
theGrassWindow.addComponentsToPane();
SwingUtilities.invokeLater(theGrassWindow);
}

}
