Java Multi-catch block

One or more catch blocks may come after a try block. A distinct exception handler must be present in each catch block. Use a Java multi-catch block, then, if you need to carry out multiple tasks when various exceptions arise.

Syntax:

try  
  {  
   // suspected code
  }  
  catch(Exception1 e)  
  {  
    // handler code
  }   
catch(Exception2 e)  
{  
  // handler code
}  

  
Things to keep in mind:
  • Only one catch block is run at a time, and only one exception is raised at a time.
  • Catch blocks must be arranged in descending order of specificity, with catch for ArithmeticException coming before catch for Exception.

Example multi-catch blocks:
public class MultipleCatchBlock {  
  
    public static void main(String[] args) {  
          
           try{    
                int arr[]=new int[5];    
                arr[5]=80/0;    
                System.out.println(arr[10]);  
               }    
               catch(ArithmeticException e)  
                  {  
                   System.out.println("Arithmetic Exception occurs");  
                  }    
               catch(ArrayIndexOutOfBoundsException e)  
                  {  
                   System.out.println("ArrayIndexOutOfBounds Exception occurs");  
                  }    
               catch(Exception e)  
                  {  
                   System.out.println("Parent Exception occurs");  
                  }             
               System.out.println("rest of the code");    
    }  
}  
Output:
Arithmetic Exception occurs
rest of the code
