我用数组做的,请问各位大神还有啥可以改进的地方么
package com.imooc.test;
import java.util.Scanner;
public class Test2 {
static boolean flag = true;
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
// 1. 名称,2. 载人量,3 载重量,4 价格 嗯?这些还需要我挨个提示么?
String[][] car = new String[4][4];
// 呐!初始化!
System.out.println("( *******(********************^^^^^----!----^^^^^********************)*******)");
System.out.println("( **欢迎来到全网最炫酷的MC吃鸡王的租车间,药!~易购窝里狗够!全场的先生们女士们这里所有的车辆任你们挑选**)");
System.out.println("( *******(********************^^^^^----!----^^^^^********************)*******)");
//拿本子记好接下来循环就要开始啦-
while(true) {
if(flag) {
System.out.println("快点的租不租,不租赶紧走 ----> 1 - (租,大哥,我租,租还不行)\t2 - (不租,走就走,谁怕谁)");
}else {
System.out.println("还租不租了 ----> 1 - (租,租呢租呢大哥,别生气)\\t2 - (不租了吧,大哥你放过我吧,我是真没钱了)");
