Display numbers from 1 to 100 without loops or conditions [closed]

Answer 1

Yes, it's possible, but it's terrible. There's any number of ways that will use either recursion or nested type creation, with exception handling for flow control. This has no real-world application IMO and should be avoided in real code at all costs.

Here's an example that uses recursive type instantiation with exception handling to control termination. It print the number is descending order, but that would be trivial to change to ascending, by just subtracting 99 (or whatever constant) from the value being printed.

class PrintVal
{
  // called with a list containing as many items as you want, less one...
  public PrintVal( List items )
  {
      System.out.println(items.size()+1);  // print the size of the list
      try { 
        items.remove( items.size()-1 );  // will throw when items is empty
        new PrintVal( items );
      }
      catch( Exception ) { /* swallow and terminate */ }
  }
}

// setup and invocation that performs the output
ArrayList strList = new ArrayList( new int[99] );
PrintVal instance = new PrintVal( strList );  // all output happens here
