所以我正在构建这个Android模拟游戏，我有一些SQL和数组问题。
在尝试从数组中的随机位置放置一些值时，我在这些行上得到了数组越界错误：
int max = 10;
int min = 0;
Random r = new Random();
int num = r.nextInt(max-min) + min;
if (west_teams[num].equals(teams[0]) ||
west_teams[num].equals(teams[1]) ||
west_teams[num].equals(teams[2]) ||
west_teams[num].equals(teams[3]) ||
west_teams[num].equals(teams[4]) ||
west_teams[num].equals(teams[5]) ||
west_teams[num].equals(teams[6]) ||
west_teams[num].equals(teams[7])
)
在SQLite问题中，我在这些行上得到Java空指针异常错误：
ContentValues cv = new ContentValues();
cv.put(TEAM, team);
cv.put(LOCATION, Location);
cv.put(PLAYER, Player);
cv.put(CRANGE, cRange);
cv.put(MRANGE, mRange);
cv.put(TRANGE, tRange);
cv.put(FREETHROW, Freethrow);
cv.put(PASS, Pass);
cv.put(DEF_REBOUND, Def_rebound);
cv.put(OFF_REBOUND, Off_rebound);
cv.put(BLOCK, Block);
cv.put(STEAL, Steal);
cv.put(STAMINA, Stamina);
return ourDatabase.insert(PLAYERS_TABLE, null, cv);
这是我的完整代码：
