Area of a Square and Rectangle using overloaded constructor

Code:

import java.util.*;

class area
{
   
   void all(int a)
  {
      int k;
     
        k=a*a;
    
       System.out.println("The Area of the Square is "+k);
      }
    void all(int b,int c)
  {
      int k;
      k=b*c;
    
       System.out.println("The Area of the Rectangle is "+k);
      }
}
class reca
{
public static void main(String args[])
{
    int a,b,c;
    Scanner in=new Scanner(System.in);
      System.out.print("Sides of Square= ");
    a=in.nextInt();
    area obj=new area();
  obj.all(a);
    System.out.print("Height of rectangle= ");
   b=in.nextInt();
     System.out.print("Breadth of rectangle= ");
      c=in.nextInt();
    obj.all(b,c);
   
}
}
