Question

我的程序是“战略游戏”，用户可以自行制作军队和化身。我的问题是，当用户不得不为自己的军队购买士兵时，我不知道如何使变量记住结果和用户可以买另一名士兵。我来自捷克共和国，所以在线上可以寻求帮助。

int zustatek = 0; //residue

int penize = 50;//money
ArrayList<Vojak> armada = new ArrayList<Vojak>();//army
do {
System.out.println("Jaké si vybereš?"); //What you choose
System.out.println("Pešák-1(10)"); //plebs
System.out.println("Lučištník-2 (15)"); //archer
System.out.println("Jezdectvo-3 (30)"); //cavalry
System.out.println("Težká jednotka-4 (50)"); //hevy soldier
int volbaVojaku = Integer.parseInt(sc.nextLine());//choose soldiers
Vojak vyberArmady = null;//picking soldiers
switch(volbaVojaku) {
case 1:

      System.out.println("A kolik jich cheš?");//how many soldiers do you want?
        int pocet = Integer.parseInt(sc.nextLine());//number of soldiers
for(int i =0; i < pocet ;i++) {
     Zbran mec = new Zbran(0,0,0,10,"meč");//weapon
    Vojak pesak = new Pesak(nazevJednotky,0,0,0,mec,vysledekBrneni);//soldier
    vyberArmady = pesak;
    armada.add(pesak);//army
    System.out.println(pesak);
 }

pocet *=10;
zustatek = penize - pocet;
System.out.println("Zůstalo ti: " + zustatek);//Result how many user have
break;

Answer 1

我认为您应该将剩余金额计算更改为此：

pocet *=10;
penize = penize - pocet;
System.out.println("Zůstalo ti: " + penize);//Result how many user have

每次购买时，初始货币价值（笔数）都会减少并保存，您实际上不必保存剩余的钱。
