	public static String zeroAddzdy(String string,int data){
		String newString = "";
		String zero = "";
		int strlength = string.length();
		System.out.println(strlength);
		if(strlength >= data){
			newString = string.substring(0,data);  
		}else{
			int i = data - strlength;
			for (int j = 0; j < i; j++) {
				zero = zero + "0";
			}
			newString = zero + string;
		}
		return newString;
