• Exception and Error both are sub classes of java.lang.Throwable class.
• We can handle Exceptions at runtime but Errors we can not handle.
• Exceptions are the objects representing the logical errors that occur at run time and makes JVM enters into the state of  "ambiguity".
• The objects which are automatically created by the JVM for representing these run time errors are known as Exceptions.
• An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch. Most such errors are abnormal conditions.

  Difference Between Exceptions and Errors

• If exception occurs we can handle it by using try and catch block. If Error occurs we can handle it program execution need to be terminated.
• In Exception we have two types
  1. Checked Exception
  2.Unchecked Exceptions
• Error are by default unchecked exceptions.
• Exceptions are related to application where ad Error are related to environment in which application is running.
• Exception are of type java.lang.Exception
• Errors are of type java.lang.Error
• Error will run at run time.
• In Exceptions Checked Exceptions will known to compiler so we need to handle these exceptions at compile time itself otherwise compile time Error will come.
• Unchecked Exception will come at run time need to handle by using try and catch blocks.
