When you select hibernation from the Shutdown menu,all your applications as well as their location on your desktop come up the next time you start up your computer.It can be enabled with Windows 2000 as follows;
Open Go to the Control Panel --> Power Options.
Click on the Hibernate tab and check Enable hibernation support.
Since hibernation takes what is in memory and writes it to disk,the amount of hard drive space needed is the same as the amount of memory you have.
This can be done by using a command line utility called uptime. You can also use it to check for remote machine.
Uptime [server] [/s ] [/a] [/d:mm/dd/yyyy | /p:n] [/heartbeat] [/? | /help]
server Name or IP address of remote server to process.
/s Display key system events and statistics.
/a Display application failure events (assumes /s).
/d Only calculate for events after mm/dd/yyyy.
/p Only calculate for events in the previous n days.
/heartbeat Turn on/off the system's heartbeat
/? Basic usage.
/help Additional usage information.
Although a subclass inherits all of the method and variables from a parent class, it does not inherit constructors.
There are only two ways in which a class can gain a constructor; either you write the constructor, or, because you have not written any constructors, the class has a single default constructor. A parent constructor is always called to a child constructor. Like methods, constructors can call non-private constructors of its immediate superclass.
Often you define a constructor that takes arguments and you want to use those arguments to control the construction of the parent part of an object. You can invoke a particular parent class constructor as part of a child class initialization by using the keyword super from the child constructor’s first line. To control the invocation of the specific constrictor, you must provide the appropriate arguments to super ( ). When there is no call to super with arguments, the parent constructor with zero arguments is called implicitly. In this case, if there is no parent constructor with zero arguments, a complier error results.
The call to super ( ) can take any number of argument appropriate to the various constructors available in the parent class, but it must be the first statement in the constructor.
