{
	int a;
	public OverLoadconstructor() 
            {
		System.out.println(a);
	    }
	
	OverLoadconstructor(int a)
            {
		this();
		this.a=a;
		System.out.println(a);
	    }
     }
class mainclass
   {
	public static void main(String[] args) 
        {	
		OverLoadconstructor a = new OverLoadconstructor(28);
	}
}
