JButton with padding between its border and the button itself

I've a JButton that has its background green-colored and its border as a LineBorder. I would like to insert a space between the button and the border, a kind of padding. I've tried with setMargin(new Insets(x,y,t,z)) but it seems not working. This is my piece of code.

JButton JBtn=new JButton("sdfd");
JBtn.setBorder(BorderFactory.createLineBorder(Color.CYAN,5));
JBtn.setBackground(Color.GREEN);
JBtn.setMargin(new Insets(5,5,10,10));

Any advice?

The borders are part of the button and clicking on them will click the button. You can set the background as green, then paint borders over the background:

jBtn.setBackground(Color.GREEN);
jBtn.setBorder(BorderFactory.createCompoundBorder(
               BorderFactory.createLineBorder(Color.CYAN, 5),
               BorderFactory.createLineBorder(Color.BLACK, 20)));

enter image description here

I've tried with setMargin(new Insets(x,y,t,z)) but it seems not working.

Because if you read the documentation for setMargin you'll see that

[...] if a non-default border is set on the button, it is that Border object's responsibility to create the appropriate margin space (else this property will effectively be ignored).

Also, reserve uppercase names for classes, rename JBtn to jBtn.

The change to the Border is changing the way the margins work (they don't seem to be included in the decisions for determining the layout any more).

Instead, you can use a CompoundBorder, for example...

JBtn.setBorder(BorderFactory.createCompoundBorder(
        BorderFactory.createLineBorder(Color.CYAN, 5), 
        BorderFactory.createEmptyBorder(5, 5, 10, 10)));
