Question

how to draw a smile in a java with not using inbuilt functions??

Answer 1

I'll show you how to create a "Hello world" application in Java:

public class Main
{
    public static void main(String[] args)
    {
        System.out.println("Hello world");
    }
}

System.out.println prints a line on the output. If you have multiple of these, you can print text line by line.

Use these to print out something, like this:

  *
   *
*   *
    *
    *
*   *
   *
  *

Tip: this will need eight System.out.println calls.

Post your solution. ;)
