The try-block is a high wire your program balances on, the catch block is the safety net. The program executes the try block as far as it can. If it fails, it'll drop off at some point and land in the safety net. If it succeeds, the net isn't used.

but why some codes need to use try catch?

for example

try

{

UIManager.setLookAndFeel(getSystemLookAndFeelName());

SwingUtilities.upadateComponentTreeUI;

catch(Exception e)

{

}
