In Java, both throw and throws are used in exception handling, but they serve distinct purposes and are used in different contexts.
throw Keyword
The throw keyword is used to explicitly throw an exception from a method or block of code. It is typically used when you want to signal an error condition or create a custom exception.
Key Characteristics:
Usage: It is used inside a method or block of code.
Type of Exceptions: It can throw both checked and unchecked exceptions, but only one exception can be thrown at a time.
Syntax: The throw keyword is followed by an instance of an exception class.
Flow of Execution: The program stops execution immediately after the throw statement unless the exception is caught in a try-catch block.
Example:
public class Example {public static void main(String[] args) {try {throw new ArithmeticException("Division by zero");} catch (ArithmeticException e) {System.out.println("Caught exception: " + e.getMessage());}}}Copied!âś•CopyOutput:
