public static void main(String [] args)
{
int ar[]={5,4,6,7,8};
System.out.println("the number of array elements are: ",ar.length);
}
}
Explanation:
The above program is created in java language in which Subject is a class name.Inside Subject class , there is main method.

spanning-tree portfast bpduguard
Explanation:
spanning- tree protocol (STP) is a layer 2 protocol in the OSI model. It is automatically configured in a switch to prevent continual looping of BPDUs, to avoid traffic congestion. The fastport bpduguard is only applicable in non-trunking access in a switch. It is more secure to configure the fastport mode in switch port connected directly to a node, because there are still bpdus transfer in a switch to switch connection.
BPDUs Guard ensures that inferior bpdus are blocked, allowing STP to shut an access port in this regard.
A row, which is also called a tuple.
