Java catch multiple exceptions

Java Multi catch block

If you have to perform different tasks at the occurrence of different Exceptions, use java multi catch block.
Let's see a simple example of java multi-catch block.
  1. public class TestMultipleCatchBlock{  
  2.   public static void main(String args[]){  
  3.    try{  
  4.     int a[]=new int[5];  
  5.     a[5]=30/0;  
  6.    }  
  7.    catch(ArithmeticException e){System.out.println("task1 is completed");}  
  8.    catch(ArrayIndexOutOfBoundsException e){System.out.println("task 2 completed");}  
  9.    catch(Exception e){System.out.println("common task completed");}  
  10.   
  11.    System.out.println("rest of the code...");  
  12.  }  
  13. }  
Output:task1 completed
       rest of the code..

Another Example :

class TestMultipleCatchBlock1{  

  public static void main(String args[]){  

  1.    try{  
  2.     int a[]=new int[5];  
  3.     a[5]=30/0;  
  4.    }  
  5.    catch(Exception e){System.out.println("common task completed");}  
  6.    catch(ArithmeticException e){System.out.println("task1 is completed");}  
  7.    catch(ArrayIndexOutOfBoundsException e){System.out.println("task 2 completed");}  
  8.    System.out.println("rest of the code...");  
  9.  }  
  10. }  
Output : Compile-time error
