Introduction to Java Exception Handling

What is Exception Handling?

Exception Handling in Java is a mechanism to handle runtime errors so that the normal flow of the program can be maintained.

An exception is an unwanted or unexpected event that occurs during program execution and disrupts the normal flow of instructions.

    public static void main(String[] args) {

        try {
            int a = 10;
            int b = 0;

            int result = a / b; // Exception occurs here

            System.out.println(result);
        } 
        catch (ArithmeticException e) {
            System.out.println("Cannot divide by zero");
        }
    }
