In core applications we can handle the exceptions by using
try &catch blocks.

ex:
class excep
{
public static void main(String[] args)
{
try
{
System.out.println(2/0);
}
catch(Exception e)
{
System.out.println(e);
}

}
}

in core java, we can handle the exception by the following 
key words
1.try
2.catch
3.finally
4.throws(it throws only predefined exception)
5.throw(it throw both predefined and userdefined exception)
