Method

voidmakeSameSize(JComponent... comps)
Makes all Compontens the same Size 
if (comps.length == 0) {
    return;
int max = 0;
for (JComponent comp1 : comps) {
    int w = comp1.getPreferredSize().width;
    max = w > max ? w : max;
Dimension dim = new Dimension(max, comps[0].getPreferredSize().height);
for (JComponent comp : comps) {
    comp.setPreferredSize(dim);
voidmakeSameSize(JComponent[] comps)
make Same Size 
if (comps.length == 0) {
    return;
int max = 0;
for (int i = 0; i < comps.length; i++) {
    int w = comps[i].getPreferredSize().width;
    max = w > max ? w : max;
Dimension dim = new Dimension(max, comps[0].getPreferredSize().height);
for (int i = 0; i < comps.length; i++) {
    comps[i].setPreferredSize(dim);
TminSize(T comp, int width)
Sets the minimum size of the JComponent 
if (comp == null) {
    return null;
comp.setMinimumSize(new Dimension(width, comp.getMinimumSize().height));
return comp;
BufferedImagepaint(final Component c, Dimension size)
Paint a Component as a BufferedImage using its preferred size. 
if (size == null)
    size = c.getPreferredSize();
final BufferedImage bi = new BufferedImage(size.width, size.height, BufferedImage.TYPE_INT_ARGB);
try {
    Runnable runnable1 = new Runnable() {
        private void revalidate(Component c) {
            if (c instanceof Container) {
                Container c2 = (Container) c;
...
DimensionpreferredSize(JComponent component)
preferred Size 
Dimension size = component.getPreferredSize();
component.setSize(size);
return size;
voidresize(JComponent component, Dimension size)
resize 
component.setPreferredSize(size);
component.setMaximumSize(size);
component.setMinimumSize(size);
voidresizeComponentWidth(JComponent currentComponent, double maxComponentWidth)
resize Component Width 
currentComponent.setPreferredSize(
        new Dimension((int) maxComponentWidth, (int) currentComponent.getPreferredSize().getHeight()));
currentComponent.setMaximumSize(
        new Dimension((int) maxComponentWidth, (int) currentComponent.getMaximumSize().getHeight()));
currentComponent.setMinimumSize(
        new Dimension((int) maxComponentWidth, (int) currentComponent.getMinimumSize().getHeight()));
voidrestrictWindowMinimumSize(final Window wnd, final Dimension minSize)
Adds listener to window that ensures that the window is not resized less then specified size. 
restrictMinimumSizeImpl(wnd, minSize);
DimensionsameSize(JComponent[] components)
same Size 
int width = 0;
int height = 0;
for (int i = 0; i < components.length; i++) {
    Dimension size = components[i].getPreferredSize();
    width = Math.max(width, size.width);
    height = Math.max(height, size.height);
Dimension result = new Dimension(width, height);
...
voidsaveComponentSize(JComponent comp, Preferences prefs, String name)
Save the size of a JComponent to a package Preferences object. 
Dimension dims = null;
if (comp instanceof JViewport) {
    dims = ((JViewport) comp).getExtentSize();
} else {
    dims = comp.getSize();
prefs.putInt(name + "_width", dims.width);
prefs.putInt(name + "_height", dims.height);
