oops interface called varibletest

Question

create an interface called VariableTest Which contains A method called disp() and 2 variables x,y which are integers and whose value is set as 10 and 20 . create a class called VarLntTest which impliments this Interface . the disp() method should display a message "inside interface-variableTest and method disp" write a method called display() within VarIntTest class which prints the value of x

CAN U GUYS PLZ HELP ME TO FIND OUT THIS ANS AND PLZ GIVE EXPLAANTION OF THIS PROBLEM TOO ..
I WANT TO KNOW THE LOGIC THTS Y ..

Unfortunately the question you've been give doesn't make much sense since an interface in C# can only contain methods properties indexers or events. It cannot contain variables. However in order to do something we'll put the variables in the class which implements the interface: using System; interface VariableTest { void disp(); } class VrLntTest : VariableTest { int x = 10; int y = 20; // this implements the interface's disp method public void disp() { Console.WriteLine(inside interface-variableTest and method disp); } public void display() { Console.WriteLine(the value of x is {0} x); } } class Test { static void Main() { VrLntTest vlt = new VrLntTest(); // create a new VrLnTest object vlt.disp(); // call disp method vlt.display(); // call display method; /* Now assign the VrLntTest object to a VariableTest variable. This is allowed because the former implements the latter. Also demonstrate that we can call the disp method via a VariableTest variable. */ VariableTest vt = vlt; vt.disp(); // call disp method via interface variable Console.ReadKey(); } } The output should be: inside interface-variableTest and method disp the value of x is 10 inside interface-variableTest and method disp Notice that you'll get a compiler warning that 'y' is assigned but is never used. Just ignore this.
