The error occurs because e1 is defined inside the try block and hence it is local to try System .out. printing (e1 . i) is outside try and is again proven to generate checked exceptions. To avoid this problem, define e1 outside the try block and inside the main () so that it will be available to all other parts of the main (), as shown below.
