Swipe to start coding

Practice using multiple catch blocks to handle specific exception types in PHP. Build on your understanding of built-in exception classes by writing a function that throws different exceptions based on input.

  • Throw an InvalidArgumentException if the argument is not an integer.
  • Throw a RuntimeException if the argument is a negative integer.
  • Return the argument multiplied by 2 for valid input.
