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.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.advantages of Exception handling in java
1) Separating normal code from exception handling code to avoid abnormal
termination of program.
2) Categorizing in to different types of Exceptions so that rather than
handling all exceptions with Exception root class we can handle with specific
exceptions. It is recommended to handle exceptions with specific Exception
instead of handling with Exception root class.
3) Call stack mechanism : If a method throws an exception and it is not handled
immediately, then that exception is propagated or thrown to the caller of that
method. This propogation continues till it finds an appropriate exception
handler,if it finds handler it would be handled otherwise program terminates
abruptly.exception handling in java example
public class Exception8 {
public static void main(String[]args)
{
fun1();
fun2();
}
static void fun1()
{
fun3();
}
static void fun2()
{
fun3();
}
static void fun3()
{
try {
System.out.println(20/0);
}
catch(ArithmeticException e)
{
System.out.println("Zero divison ");
}
}
