Java Nested try block

Java Nested try block

The try block within a try block is known as nested try block in java.

Why use nested try block

Sometimes a situation may arise where a part of a block may cause one error and the entire block itself may cause another error. In such cases, exception handlers have to be nested.

Syntax:

....  

try  

{  

    statement 1;  

    statement 2;  

    try  

    {  

        statement 1;  

        statement 2;  

    }  

    catch(Exception e)  

    {  

    }  

}  

catch(Exception e)  

{  

}  

....  

Java nested try example

Let's see a simple example of java nested try block.

class Excep6{  

 public static void main(String args[]){  

  try{  

    try{  

     System.out.println("going to divide");  

     int b =39/0;  

    }catch(ArithmeticException e){System.out.println(e);}  

   

    try{  

    int a[]=new int[5];  

    a[5]=4;  

    }catch(ArrayIndexOutOfBoundsException e){System.out.println(e);}  

     

    System.out.println("other statement);  

  }catch(Exception e){System.out.println("handeled");}  

  

  System.out.println("normal flow..");  

 }  

}
