public class UseOfConstructor {
    int h,w,l,H,W,L;
    UseOfConstructor(int h,int w,int l)
    {
        H=h;
        W=w;
        L=l;     
    }
            
    int area(int H,int W,int L)
    {
     return(H*W*L);
    }
    public static void main(String args[])
    {
     int H,W,L;
     int Area;
     Scanner obj=new Scanner(System.in);
     System.out.println("Enter Height = ");
     H=obj.nextInt();
     System.out.println("Enter Width = ");
     W=obj.nextInt();
     System.out.println("Enter Length = ");
     L=obj.nextInt();
     UseOfConstructor cls=new UseOfConstructor(H, W, L); 
     System.out.println("The Area Of Box = "+cls.area(H, W, L));
    } 
    
}

O/P:-

run:
Enter Height = 
2
Enter Width = 
3
Enter Length = 
5
The Area Of Box = 30
