Try with Multiple Catch Blocks: One try block can have multiple catch blocks to handle different types of exceptions occur in different lines of code.
Program to read 2 numbers and perform division: In this program, we need to handle two exceptions
| InputMismatchException: If the input is invalid ArithmeticException: If the denominator is zero |
Code Program:
| import java.util.Scanner; import java.util.InputMismatchException; class Code { public static void main(String[] args) { Scanner sc = new Scanner(System.in); try { System.out.println(“Enter 2 numbers : “); int a = sc.nextInt(); int b = sc.nextInt(); int c = a/b; System.out.println(“Sum is : ” + c); } catch (InputMismatchException e1) { System.out.println(“Exception : Invalid input values”); } catch (ArithmeticException e2) { System.out.println(“Exception : Denominator should not be zero”); } } } |
We can handle Multiple exceptions in following ways:
| Try with Multiple Catch blocks: It is useful to provide different message to different exceptions. | catch object using Exception class: Same logic to handle all exceptions | Using Bitwise OR: Related exceptions can handle with single catch block |
| try { } catch(Exception1 e1) { } catch(Exception2 e2) { } | try { } catch(Exception e) { } | try { } catch(Exception1 | Exception2 e) { } |
Exceptions Hierarchy:
- Throwable is the super class of all exception classes.
- We can handle only Exceptions in Java not Errors.
