题目：实验2： 托运行李 程序模板 请按模板要求，将【代码】替换为程序代码。 BaggageAndMony.java import java.util.Scanner; public class BaggageAndMony { public static void main(String args[]) { int trainCharge=12; //火车托运计费:每公斤12元 int carCharge=22; //汽车托运计费:每公斤12元 double planeCharge = 0.062 ;//飞机托运计费:每克0.062元 Scanner reader=new Scanner(System.in); double weight,charge; System.out.printf("输入行李重量:"); weight = reader.nextDouble(); System.out.printf("行李重量:%f公斤(kg)\n",weight); System.out.printf("需要计费的重量:%d(kg)\n",(int)weight); 【代码1】 //将表达式(int)weight*trainCharge的值赋值给charge System.out.printf("用火车托运(%d元/kg),费用:%f元\n",trainCharge,charge); System.out.printf("需要计费的重量:%d(kg)\n",(int)(weight+0.5)); 【代码2】】//将表达式(int)(weight+0.5)*carCharge的值赋值给charge System.out.printf("用汽车托运(%d元/kg),费用:%f元\n",carCharge,charge); System.out.printf("行李重量:%f克(g)\n",weight*1000); System.out.printf("需要计费的重量:%d(g)\n",(int)(weight*1000+0.5)); 【代码3】//将表达式(int)(weight*1000+0.5)*planeCharge的值赋值给charge System.out.printf("用飞机托运(%f元/g),费用:%f元\n", planeCharge,charge); } }
