setting horizontal and vertical margins

Question

What is the method to set horizontal and vertical margins in a panel? (The same we have in html style="margins:30px")

As others have mentioned, you should just use a Border (there is an EmptyBorder class in Swing to just do that). However, I would not recommend hard-coding the size of margins in a panel, especially using pixels (which size can change A LOT depending on the resolution of monitors). It is preferrable to use javax.swing.LayoutStyle to calculate the right margins. Or better, use a LayoutManager that does it for you. — jfpoilpret, May 02 '11 at 08:23

setBorder(BorderFactory.createEmptyBorder(int top, int left, int bottom, int right));

And for more details you can read the documentation about BorderFactory

Don't know html, so just guessing on possible equivalents :-)

to set some space between a component's bounding rectangle and its content, the property to set is its Border
the spacing between the different components in a container is controlled by the LayoutManager (already mentioned). Depends on the concrete implementation how fine-grained that's configurable

Use a BorderLayout for your JPanel.

That depends highly on the kind of Panel you are using. If this refers to swing you could put a Gridbaglayout on it and specify Insets like in this example

for create basic "Gap" between JComponents by using LayoutManagers Laying Out Components Within a Container

BorderLayout(int horizontalGap, int verticalGap)

GridLayout(int rows, int cols, int hgap, int vgap)

for most complex GUI you have to

1/ multiplayed JPanels (with different LayoutManager for each of JPanel too)

2/ by using How to Use GridBagLayout (by multiplayed JPanels with different LayoutManegars for each JPanel ...)

3/ use some Custom LayoutManager

setting horizontal and vertical margins
