public class Icon implements Visible

{

/ / instance variable

//Constructor variable

Public Icon ()

{

//implementation

}

//two methods will be implemented make visible and makeInvisible with the signage and return type

//displayed below

/ public boolean makeVisible ()

{

//the implementation is registered here

public boolean makeInvisible ()

{ / /implemetation will be here

}

//other methods are of this type

Explanation:

Create an interface called Visible that includes twomethods: makeVisible and makelnvisible. Both methods should takeno parameters and should return a Boolean result. Describe how aclass might implement this interface. public interface Visible{public: boolean makeVisibleO; public boolean makelnvisibleO;

The above can be executed as a jа vascript

public class Icon implements Visible

{

/ / instance variable

//Constructor variable

Public Icon ()

{

//implementation

}

//two methods will be implemented make visible and makeInvisible with the signage and return type

//displayed below

/ public boolean makeVisible ()

{

//the implementation is registered here

public boolean makeInvisible ()

{ / /implemetation will be here

}

//other methods are of this type
