computetotalprice.java

还不错的java基本实例

package ch2;
import java.text.NumberFormat;
import java.util.Scanner;;
public class ComputeTotalPrice {
	public static void main( String[] args){
		double totalPrice,UnitPrice;
		float unitWeight;
		int numberOfUnits;
		NumberFormat currencyformatter=NumberFormat.getCurrencyInstance();
		Scanner scan=new Scanner(System.in);
		System.out.print("输入单位重量：");
		unitWeight=scan.nextFloat();
		System.out.print("输入卖出的包数：");
		numberOfUnits=scan.nextInt();
		System.out.print("输入每千克的价格：");
		UnitPrice=scan.nextDouble();
		totalPrice=unitWeight*numberOfUnits*UnitPrice;
		System.out.print("销售总额为："+currencyformatter.format(totalPrice));
	}
}
