Question

Define a class to overload the method display as follows:

void display():	To print the following format using nested looр 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5
void display(int n):	To print the square root of each digit of the given number
Example:	n = 4329 output -3.0      1.414213562      1.732050808      2.0

Answer 1

class Overload_X
{
    public void display()
    {
       for(int i=1;i<=5;i++)
       {
          for(int j=1;j<=i;j++)
          {
              System.out.print(j+" ");
          }
              System.out.println();
       }
    }
    public void display(int n)
    {
       while(n>0)
       {
              int r=n%10;
              System.out.println(Math.sqrt(r));
              n=n/10;
       }
    }
}
