Try and Catch

Try - Make an attempt or effort to do something
Catch - Intercept and Hold

Syntax:

try
{
statement(s);
}

catch (Exception Handler Tag)
{
statement(s);
}


The try and catch  allows you to test a block of errors. Once it encounters a block of errors in the try, it passes it to the tag. A tag is a variable that hold the exception. The statements under the catch are to be executed once the try receives an error (it catches the errors from the try).

Exception Handler is an exception. An exception an error. Famous exceptions are IOException and NumberFormatException.
