Error Vs Exception In Java pramodbablad April 15, 2015 3 Both java.lang.Error and java.lang.Exception classes are sub classes of java.lang.Throwable class, but there exist some error exception from hresult 0x800a03ec significant differences between them. java.lang.Error class represents the errors which are error exception handling console input mainly caused by the environment in which application is running. For example, OutOfMemoryError occurs when JVM runs out of memory

or StackOverflowError occurs when stack overflows. Where as java.lang.Exception class represents the exceptions which are mainly caused by the application itself. For example, NullPointerException occurs when an application tries to http://php.net/manual/en/class.errorexception.php access null object or ClassCastException occurs when an application tries to cast incompatible class types. In this article, we will discuss the differences between Error and Exception in java. Below is the list of differences between Error and Exception in java. Error Vs Exception In Java : 1) Recovering from Error is not possible. The only solution to errors http://javaconceptoftheday.com/difference-between-error-vs-exception-in-java/ is to terminate the execution. Where as you can recover from Exception by using either try-catch blocks or throwing exception back to caller. 2) You will not be able to handle the Errors using try-catch blocks. Even if you handle them using try-catch blocks, your application will not recover if they happen. On the other hand, Exceptions can be handled using try-catch blocks and can make program flow normal if they happen. 3) Exceptions in java are divided into two categories - checked and unchecked. Where as all Errors belongs to only one category i.e unchecked. Click here for more info on Checked and Unchecked Exceptions. 4) Compiler will not have any knowledge about unchecked exceptions which include Errors and sub classes of RunTimeException because they happen at run time. Where as compiler will have knowledge about checked Exceptions. Compiler will force you to keep try-catch blocks if it sees any statements which may throw checked exceptions. 5) Exceptions are related to application where as Errors are related to environment in which application is running. Below is
processing – often changing the normal flow of program execution. It is provided by specialized programming language constructs or computer hardware mechanisms. In general, an exception is handled (resolved) by saving the current state of https://en.wikipedia.org/wiki/Exception_handling execution in a predefined place and switching the execution to a specific subroutine known as an exception handler. If exceptions are continuable, the handler may later resume the execution at the original location using the saved information. For example, a floating point divide by zero exception will typically, by default, allow the program to be resumed, while an out of memory condition might not be resolvable transparently. error exception Alternative approaches to exception handling in software are error checking, which maintains normal program flow with later explicit checks for contingencies reported using special return values or some auxiliary global variable such as C's errno or floating point status flags; or input validation to preemptively filter exceptional cases. Some programmers write software with error reporting features that collect details that may be helpful in fixing error exception handling the problem, and display those details on the screen, or store them to a file such as a core dump, or in some cases an automatic error reporting system such as Windows Error Reporting can automatically phone home and email those details to the programmers.

It is intended to support error detection and redirects the program flow to error handling service routines.
