Java provides a robust mechanism for handling runtime errors through exception handling. The following keywords are used to manage exceptions effectively:
try
The try keyword is used to define a block of code that might throw an exception. It allows you to test code for errors during execution. If an exception occurs, it is passed to the corresponding catch block.
Example:
try {int result = 10 / 0; // This will throw ArithmeticException} catch (ArithmeticException e) {System.out.println("Caught exception: " + e.getMessage());}Copied!âś•Copycatch
The catch keyword is used to handle exceptions thrown in the associated try block. You can have multiple catch blocks to handle different types of exceptions.
Example:
try {int[] numbers = {1, 2, 3};System.out.println(numbers[10]); // Throws ArrayIndexOutOfBoundsException} catch (ArrayIndexOutOfBoundsException e) {System.out.println("Array index out of bounds: " + e.getMessage());}Copied!âś•Copyfinally
