Hello. I decided to start working with the Swing library (from IDEA in Ubuntu). When working with Form in Designer, the following (rather “stylish”) window is obtained 
And after compiling and running, the following window appears (no longer so “stylish”) 
Is there an easy way to make the style of the running window coincide with that in the Form. Or maybe other ways? Thank you in advance!

There are several built-in to choose from, but in the idea it may well be its own kind.UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");- SergeyUIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAn‌​dFeel");programUIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAn‌​dFeel");Through setting a property on the command linejava -Dswing.defaultlaf=javax.swing.plaf.nimbus.NimbusLookAndFeel MyApp- Sergey
