Question

Define a class to overload the function print as follows:

void print()	to print the following format
	1	1	1	1
	2	2	2	2
	3	3	3	3
	4	4	4	4
	5	5	5	5

void print(int n)	To check whether the number is a lead number. A lead number is one whose sum of even digits is equal to the sum of odd digits.
	e.g. 3669 odd digits sum = 3 + 9 = 12 even digits sum = 6 + 6 = 12 3669 is a lead number.

Answer 1

public class Prmtclass
{
   // instance variables - replace the example 
   below with your own
 public void print() 
{
    for(int i=1;i<=5;i++)
       {for(int j=1;j<=5;j++)
           System.out.print(i+" ");
       System.out.println("\n");}
}
public void print(int n)
{
   int se=0,d=0,so=0; 
   while (n>0)
   {
       d=n%10;
       if (d%2=0)
           se+=d;
       else
            so+=d;
        n/=10;
   } 
   if (se==so)
       System.out.println("Lead number");
   else
   System.out.println("Not a Lead number");
}
public static void main(String [] args)
{
     Printclass ob=new Printclass();
     ob. print(); 
     ob.print(1542);
  }
}
