 { int endValue = Integer.parseInt(args[0]);
  int j = 1;
  int temp = 1;
  
  for(int i = 1;j <= endValue;i++)
  {
   for(;j <= temp + 3;j++)
    System.out.print(j + " ");
   temp = j;
   
   System.out.println("");
  }

		for(;start <= stop;)
		{
			System.out.print(start + " ");
			start += Integer.parseInt(args[2]);
		}
	}
}

public class SumOfEvenNumbersInBetween
{
        public static void main(String[] args)
	{
		int start = Integer.parseInt(args[0]) + 1;

                int stop  = Integer.parseInt(args[1]);

                int sum = 0;
		for (; start < stop; start ++)
		{
			if(start %2 == 0)
				sum = sum + start;
		}
		
		System.out.println(" Sum of Even No in given Range is " + sum);
		
	}
}

Java Program 002
