Question

The following BuildingApplication class is incomplete. You need to complete the missing lines of codes in:

 inner class- Verification

 main method

Note: Assume that the building occupies the middle of the plot horizontally and vertically. To approve a building application, a building needs to provide a minimum clearance of 1m from the edge of the plot. i.e., the difference between plot width and building width should be at least 2m; the difference between the plot length and building length should be at least 2m.

public class BuildingApplication

{ double plotLength;

double plotWidth;

double buildingLength;

double buildingWidth; boolean approved = false;

public BuildingApplication (double plotLength, double plotWidth, double buildingLength, double buildingWidth)

{ this.plotLength = plotLength;

this.plotWidth = plotWidth;

this.buildingLength = buildingLength;

this.buildingWidth = buildingWidth; }

/inner class class Verification

{ boolean objection ;

private static final double MINIMUM_REQUIRED = 2.0;

//constructor

public Verification()

{ objection = false; }

// end of constructor- Verification

boolean check()

{ // to return true if there is a minimum clearance of 1m in all sides of the building //Missing lines of codes have to be completed }

// end of check method }

// end of inner class

public void displayApproval()

{ Verification test = new Verification();

approved = test.check();

if(approved)

System.out.println("Building plan Approved");

else

System.out.println("Building plan Rejected");}

public static void main(String [] args)

{ /* Create two BuildingApplication objects and test whether they are approved or not. * You need to create one Building object that can be approved and the other that *cannot be approved */ //Missing lines of codes have to be completed }

// end of main method }

// end of BuildingApplication clas

// Bean class

   Verification test = new Verification();

//Test driver class

package sample1;

public class test{
public static void main(String [] args)
{
   BuildingApplication ba1=new BuildingApplication(102.0,52.0,101.0, 51.0);
   BuildingApplication ba2=new BuildingApplication(104.0,54.0,102.0, 52.0);
   ba1.displayApproval();
   ba2.displayApproval();
}
