Question

Create an interface named Shippable with a method named getVolume and another named getWeight. Neither has parameters and both return a number

Answer 1

interface Shippable //Declaring the interface
{
public int getVolume(); //Abstract method getVolume()
public int getWeight(); //Abstract method getWeight()
}
class Temp implements Shippable //Class Temp is implementing the Interface
{
int volume=6,weight=45;
public int getVolume() //Adding the definition of getVolume() method
{
return volume;
}
public int getWeight() //Adding the definition of getWeight() method
{
return weight;
}
}
public class Main
{
  
   public static void main(String[] args) {
       Temp t = new Temp(); //Creating the Object of Temp Class
       int a,b;
       a = t.getVolume(); //Calling the getVolume() method
       b = t.getWeight(); //Calling the getWeight() method
       System.out.println("Volume is: "+a); //Printing the Volume
       System.out.println("Weight is: "+b); //Printing the Weight
   }
}

Output:-
