It allows you to write code that handles exceptions that may be thrown during the execution of your program. we can also handle different types of exceptions with multiple catch blocks. -- suppose we write few lines of code and we donot know which line can generate exception but we know donot which types of exception can be generated. In this case we can use try with multiple catch e.g int num=4; int arr[]={3,4,5}; try{ int result=40/num; //we donot know what does user pass the value of num then we put inside try System.out.println(arr[result]); //we donot know what the value of result but we know index of array allowed is 0 to 2 therefore we put this statement also in try } catch(ArithmeticException ae){ System.out.println(ae); } catch(ArrayIndexOutOfBoundsException aio){ System.out.println(aio); } # Handling parents and child Exception both -- when catching both child and parent exceptions in a try-catch block, it is generally recommended to catch the child exceptions before the parent exception. -- The reason for this is that if you catch the parent exception before the child exception, the catch block for the parent exception will also catch any child exceptions that are subclasses of the parent exception. This can make it more difficult to handle the child exceptions separately. e.g int a = 10; int arr[]={3,4,5}; try{ int b = 3/a; System.out.println(arr[b]); } catch(Exception e){ System.out.print("parent class of every exception"); } catch(ArithmeticException e){ } -- this will give compile time error i.e error: exception ArithmeticException has already been caught by Exception class Right way: first child Exception then parents Exception int a = 10; int arr[]={3,4,5}; try{ int b = 3/a; System.out.println(arr[b]); } catch(ArithmeticException e){ } catch(Exception e){ System.out.print("parent class of every exception"); } Github repo : https://github.com/navinreddy20/Javacode.git Java:- https://bit.ly/JavaUdemyTelusko Spring:- https://bit.ly/SpringUdemyTelusko More Learning : Java :- https://bit.ly/3x6rr0N Python :- https://bit.ly/3GRc7JX Django :- https://bit.ly/3MmoJK6 JavaScript :- https://bit.ly/3tiAlHo Node JS :- https://bit.ly/3GT4liq Rest Api :-https://bit.ly/3MjhZwt Servlet :- https://bit.ly/3Q7eA7k Spring Framework :- https://bit.ly/3xi7buh Design Patterns in Java :- https://bit.ly/3MocXiq Docker :- https://bit.ly/3xjWzLA Blockchain Tutorial :- https://bit.ly/3NSbOkc Corda Tutorial:- https://bit.ly/3thbUKa Hyperledger Fabric :- https://bit.ly/38RZCRB NoSQL Tutorial :- https://bit.ly/3aJpRuc Mysql Tutorial :- https://bit.ly/3thpr4L Data Structures using Java :- https://bit.ly/3MuJa7S Git Tutorial :- https://bit.ly/3NXyCPu Donation: PayPal Id : navinreddy20 https://www.telusko.com Ky8P70QlKNU |
