		int index = 0;
		while(number > 0){
			binary[index++] = number%2;
			number = number/2;
		}
		for(int i = index-1;i >= 0;i--){
			System.out.print(binary[i]);
		}
	}
	
	public static void main(String a[]){
		DecimalToBinary dtb = new DecimalToBinary();
		dtb.printBinaryFormat(25);
	}
}

Can we call servlet destory() from service()?
As you know, destory() is part of servlet life cycle methods, it is used to kill the servlet instance. Servlet Engine is used to call destory(). In case, if you call destory method from service(), it just execute the code written in the destory(), but it wont kill the servlet instance. destroy() will be called before killing the servlet instance by servlet engine.
