总结：请给我更好的建议 

package com.badu;import java.util.Scanner;//从键盘输入次数，通过输入的编号，输出对应的的商品价格；public class tqwe {	public static void main(String[] args) {		Scanner c = new Scanner(System.in);		int x = c.nextInt();// x是次数，number是编号，price是价格		int number[] = new int[x];		double price;		for (int i = 0; i < x; i++) {			System.out.println("请输入编号：");			number[i] = c.nextInt();			if (number[i] == 1) {				price = 3.0;				System.out.println("apples的价格是" + price);			} else if (number[i] == 2) {				price = 2.5;				System.out.println("orange的价格是" + price);			} else if (number[i] == 3) {				price = 4.1;				System.out.println("pears的价格是" + price);			} else if (number[i] == 4) {				price = 10.2;				System.out.println("graps的价格是" + price);			} else {				System.out.println("该商品不存在！！！！");				continue;			}		}	}}//6请输入编号：5该商品不存在！！！！请输入编号：3pears的价格是4.1请输入编号：2orange的价格是2.5请输入编号：1apples的价格是3.0请输入编号：3pears的价格是4.1请输入编号：4graps的价格是10.2
