error and exception in java code example
Example 1: error vs exception
Both Error and Exception are derived from Throwable in Java.
Error represents errors which are generally cannot be handled. For examples:
OutOfMemoryError, NoClassDefFoundError
Exception represents errors which can be caught and handled. For examples:
IOException, NullPointerException
Exception is divided in two categories; checked and unchecked Exception.
Checked Exception require a mandatory try-catch code block to handle it.
Unchecked Exception mostly represent programming errors (NullPointerException
or RuntimeException)
Errors are unchecked exception and the developer is not required
to do anything with these.
All the Errors are Exceptions, but the reverse is not true.
In general Errors are which nobody can control or guess when it happened,
on the other hand Exception can be guessed and can be handled.
Example 2: what is exception in java
In java exception is an object. Exceptions are created when an abnormal
situations are arised in our program. Exceptions can be created by JVM or
by our application code. All Exception classes are defined in java.lang.
In otherwords we can say Exception as run time error.
Example 3: exception in java
In java exception is an object. Exceptions are created when an abnormal
situations are arised in our program. Exceptions can be created by JVM or
by our application code. All Exception classes are defined in java.lang.
In otherwords we can say Exception as run time error. I use try & catch blocks
to handle any exceptions in my code.
I am familiar with major checked and unchecked exceptions and
handle it accordingly to make my code execution smooth
Example 4: what is exception in java
An exception is an event, which occurs during the execution of a
program, that disrupts the normal flow of the program's instructions.
