Time to Fill Water Tank Program

 

Example: General AC consultation area program.

 Sam Sir

//program name Main090.java

/* WAP to Enter Length, Width and Height of Living Hall. Calculate Square Feet

of Room, Also calculate Cube area of Air which is required to installed Air-condition.*/

// General AC consultation area program.

 

import java.util.Scanner;

public class Main090

{

public static void main(String[] args)

{

int l,w,h,total_cube_area;

System.out.print("Enter Length, Width and Height of Room in feets : ");

Scanner scan=new Scanner(System.in);

l=scan.nextInt();

w=scan.nextInt();

h=scan.nextInt();

total_cube_area=l*w*h;

System.out.printf("Total Room Cubical Area = %d \n",total_cube_area);

if (total_cube_area<=1000)

System.out.print("AC with 1 Ton Capacity will be ok");

else if (total_cube_area<=1500)

System.out.print("AC with 1.5 Ton Capacity will be ok");

else if (total_cube_area<=2000)

System.out.print("AC with 2 Ton Capacity will be ok");

else

System.out.print("Consult Air-condition Tech people to get right Spec.");

 

}

}

Output

Enter Length, Width and Height of Room in feets : 10 12 15

Total Room Cubical Area = 1800

AC with 2 Ton Capacity will be ok

 

Enter Length, Width and Height of Room in feets : 12 15 13

Total Room Cubical Area = 2340

Consult Air-condition Tech people to get right Spec.
