文件Deli.java是一个不完整的程序。该程序用于计算在deli购买物品的费用。将该程序保存至本地磁盘，并进行以下操作：
1. 阅读并理解程序；
2. 添加import语句，导入DecimalFormat和NumberFormat两个类；
3. 声明变量money为一个NumberFormat类型的对象；
4. 声明变量fmt为一个DecimalFormat类型的对象；
5. 按照下面的格式打印结果。使用格式化对象money打印price和total price，使用格式化对象fmt打印weight。

**** CS Deli ****
Unit Price:￥4.25 per pound
Weight:0.16 pounds
TOTAL:￥0.68
//**********************************************************
//主要功能：使用格式化对象money打印price和total price，使用格式化对象fmt打印weight。

System.out.println("Unit Price:"+ 8 +" per pound\n");
System.out.println("Weight:"+ 9 +" pounds\n\n");
System.out.println("TOTAL: "+ 10 );
