Difference between error and an exception? October 5, 2006
Posted by :) in JAVA.trackback
An error is an irrecoverable condition occurring at runtime. Such as OutOfMemory error. These JVM errors and you can not repair them at runtime. While exceptions are conditions that occur because of bad input etc. e.g. FileNotFoundException will be thrown if the specified file does not exist. Or a NullPointerException will take place if you try using a null reference. In most of the cases it is possible to recover from an exception (probably by giving user a feedback for entering proper values etc.).

Hi sir can you tell me why threads are said to be lightweight and please tell me what is the difference between lightweight and heavyweight components.
what is the difference between error and exception ?
main difference is
In case of exception, we can use wxception handler to overcome the exception and continue with the normal execution of the program.
There might be some checked and some unchecked exceptions.
most of the exceptions can be handled.
but in case of error, there is no error handler as such to handle those.
There are some tipical error classes such as LinkerError,VirtualMachineError,ThreadDeath etc. can not be handled explicitly. These are irrecoverable.This is the main Difference.
NOTE–> If you know anything more then please let me know.
nice explanation
thank you
why the class cannot be declared as private and protected?
bcz when we use private or protected the access of the class is limited.
when we use private we cant even try to call that class from other class
when we use protected we cant call the class from other package. but we
can use those sub classes of the protected classes any where.but by using public there is no restriction
Difference Between Throws And Throw is That the preceeded one is used for specifying that a function will throw an exception of particular type such as
public void run() throws InterruptedException
{
try
{
//some code here which generates exception
}
catch()
{
throw InterruptedException()
}
}
The Key word throw is used for Rethrowing An Exception from child Function to parent(calling) function and managing it out there
