Classification Of Exceptions

Classification of exceptions

  • Checked Exceptions or compile time exceptions, like IOException, MalformedURLException etc.

  • Compiler forces these exceptions to be caught or passed to calling program

  • Unchecked exceptions or runtime exceptions, like ArithmeticException, ArrayIndexOutofBoundsException etc.

  • Compiler does not force to handle these unchecked exceptions.

Throwing exceptions to the caller

  • Using “throws”, the called method can pass the exception to the caller.

Creating your own exception class

  • In case programmer wants to hide exception details and give summary, he can create his own exception class.
  • The user defined exception classes must extend Exception class.

Analyzing the stack trace

  • e.printStackTrace() method gives the information as to from where the exception gets thrown and path leading to it.
In addition to these two main categories, Java also includes a hierarchy of specialized exceptions, each serving a specific purpose and representing different error conditions. You can create custom exceptions by extending the Exception class or one of its subclasses to handle application-specific errors.
