Java exception handling allows us to use nested try-catch block.

Nested try-catch block means using try-catch block inside another try-catch block.

                 }catch(NullPointerException npe){
                       System.out.println("NESTED try-catch block handled - "
                                                             + "NullPointerException");
                 }
                
          }

}
/*OUTPUT
try-catch block handled - ArithmeticException
NESTED try-catch block handled - NullPointerException
