Exceptions

Exception Handlers Exception Handlers in Java are constructs used to handle exceptions that occur during the execution of a program. The primary way to handle exceptions is by using try, catch, and finally blocks. try-catch Block The try block contains code that might throw an exception. The catch block handles the exception type declared in its parameter. try { int[] arr = new int[5]; arr[10] = 50; // This will throw ArrayIndexOutOfBoundsException } catch (ArrayIndexOutOfBoundsException e) { System.out.println("Caught exception: " + e); } Multiple catch Blocks You can catch different types of exceptions separately. ...

Exception Handling Exception Handling in Java is a powerful mechanism that handles runtime errors to maintain the normal flow of application execution. Java provides a robust and object-oriented way to handle exceptions using try, catch, throw, throws, and finally blocks. Why Use Exception Handling? Avoid abnormal termination of the program. Gracefully handle unexpected situations like file not found, divide by zero, etc. Help in debugging and maintaining the code. Keywords in Exception Handling try – Defines a block of code to test for errors. catch – Defines a block of code to handle errors. finally – Defines a block of code that will always execute after try/catch, regardless of the outcome. throw – Used to explicitly throw an exception. throws – Declares exceptions that a method might throw. Example: public class ExceptionExample { public static void main(String[] args) { try { int result = 10 / 0; // ArithmeticException } catch (ArithmeticException e) { System.out.println("Error: " + e.getMessage()); } finally { System.out.println("This will always execute."); } } } Output: ...
