解决了
我编写了一个程序,它在等号之后加载字符串,并让它计算它执行了多少次。数完后,我告诉它告诉我 int 有多大。我正在寻找的值是 3,它告诉我,3。然后我将其更改为字符串,该值保持为 3。然后,我将它放入一个 4d 数组中,它告诉我值为 2。发生了什么?
代码:
int times=0;
else if (list.equals("Weapon")) {//If the word weapon is before the =
weapon = value; //take the string after the = and put it into String weapon
troopStats[times][1][weaponTimes][0] = weapon;
weaponTimes++;
System.out.println(weaponTimes+"weapontimes"+times);
}
weaponTimesStr = Integer.toString(weaponTimes);
System.out.println(weaponTimesStr+"string");
troopStats[times][1][0][1] = weaponTimesStr;
System.out.println(troopStats[times][1][0][1]+"InArray");
times++
//loops
输出:
3weapontimes //Counted the equals sign 3 times, Note that this is from the part of the
omitted code
3string // Changed the integer to a string and got 3
2InArray // Put it into an array, and got 2 back
发生了什么事?
(我知道我可以将值加 1,但我想稍后将此代码用于未知数量的事情)
为了帮助,我已经发布了整个代码:
public class TroopLoader {
static String[][][][] troopStats;
static int times = 0;
static int weaponTimes = 0;
static int armorTimes = 0;
static int animalTimes = 0;
static String weaponTimesStr;
static String armorTimesStr;
static String animalTimesStr;
static String troop;
static String weapon;
static String armor;
static String animal;
static String speed;
static int total = 0;
/*
* [][][]
*
* [total number of troops (total)]
*
* [stats] 0= name 1= weapon 2= armor 3= animal 4= speed
*
* [different things within stat]
*/

String list = troops.nextToken();

在代码的前面部分,我让程序将一个值存储在具有武器时间变量的数组位置,而不是存储武器时间变量。我的错,很抱歉浪费您的时间。
【问题讨论】:
-
我敢猜测
times不是你想的那样。 -
你能显示SSCCE吗?
weaponTimesString和weaponTimesStr是一样的吗?times可以在第 3 行和第 4 行之间更改(由另一个线程访问)吗? -
在调试器中单步执行代码时会看到什么。这种变化发生在哪一行?
-
您分配了
weaponTimesString,但您使用了weaponTimesStr。这是问题中的复制粘贴错字吗?还是在代码中? [无论如何我怀疑这是问题所在,因此这只是一个评论 - 不是答案] -
@Russell 您的 IDE 很可能使您能够插入断点并逐步运行程序,以便您可以检查每行代码的变量值。
