} finally {
  // Code executed after try / catch, used to close streams
  /*example*/ in.close();

      int data=100/0;

Java Exception handling using try...catch

    try {

      // code that generate exception
      int divideByZero = 5 / 0;
      System.out.println("Rest of code in try block");
    }
    
    catch (ArithmeticException e) {
      System.out.println("ArithmeticException => " + e.getMessage());
    }
  }
}

try catch in java

try block: code that is protected for any exceptions. and it is mandatory 
(only try)
catch block: if any exception happens during runtime in the try block, 
the catch block will catch that exception.
if any exception happens during runtime in the try block, 
control will be given to catch block.
An optional finally block gives us a chance to run the code which 
we want to execute EVERYTIME a try-catch block is completed 
– either with errors or without any error.
