A TRY block contains the program statement in which an exception can occur. Also a TRY block is always followed by CATCH block which is used to handle the exceptions that occur in TRY block. A TRY block is always followed by CATCH block.

A CATCH block is associated with a TRY block and the corresponding CATCH block is executed if an exception occurs in the try block.

Below is the JAVA Program to Explain the Try Catch Code

class TryCatch {
   public static void main(String args[]) {
     int number1, number2,number3;
     try {
        // Try block to handle code that may cause exception
        number1 = 0;                   //We Assign Number 1 with 0        
        number2 = 65;                  //We Assign Number 2 with 65
        number3 = number2 / number1;   //Now we try to divide 65 by 0 which should through an exception
                                       //and will be caught in catch block
        System.out.println("Try block message");
     } catch (ArithmeticException e) {
            // This block is to catch exception for divide-by-zero error
            System.out.println("Error: Don't divide a number by zero");
       }
     System.out.println("I'm out of try-catch block in Java.");
   }
}

Raising an Exception In the previous problem, you used a try/except statement to catch an exception. This problem deals with the opposite situation: raising an exception in the first place. One common situation in which you will want to raise an exception is where you need to indicate that some precondition that your code relies upon has not been met. (You may also see the assert statement used for this purpose, but we won’t cover that here.) Write a function...

A brief explanation is needed for these true/false questions. a) A method that contains a try-catch-finally structure may also have a “throws” declaration. b) An arithmetic exception such as division by zero can be avoided by careful programming while an I/O exception such as file not found may occur regardless of the precautions taken by the programmer. c) Lets assume that you create an object x of the Object class. You can assign any object (objects of other classes) to...
