Explanation:
If a device is putting data into the computer in the form of text, sound, images, button presses etc. then it is an input device, if the device is outputting things from the computer such as sound, movement, printing, images etc., then it is an output device. ... Therefore it is an input device.
Answer:
Explanation:
Explicit Dependencies
<u>It states that the classes and methods should explicitly require , via constructor or method parameters all the collaborating objects that are required for the function to work properly .</u>
Classes with the implicit dependencies cost very high for the maintenance than the explicit dependencies .
Even , the implicit dependencies are difficult to test as they are tightly coupled to their collaborators .
Explanation:
Following are the difference between overriding and overloading
(1) Method overloading means method having same name but different parameter or method signature Whereas Method overriding means method having same name and same parameter or signature.
(2) Method overloading is achieved the compile time Polymorphism whereas Method overriding is achieved the Run time Polymorphism .
(3 ) In method overriding child class have facility to provide a specific implementation of a method which is already defined by parent class method whereas there is no such facility is available in method overloading
(4 )Programming structure of method overloading
class test
{
void fun()
{
// statement
}
void fun(int b)
{
// statement
}
}
In this fun() method name is same but different signature I.e void fun() and void fun(int a);
Programming structure of method overriding
class parent
{
void fun()
{
// statement in parent class
}
}
class child extends test
{
void fun()
{
// override the statement in child class
}
}
In this fun() method have same name and same signature in both class
