高手请进，请教关于如何判断定长数组中的值问题。

[feijipaopao]

比如说我有一个数组
String[] attrNames = { "Ind_Caller_Number_1","Ind_RBT_1","Ind_Group_ID_1",
"Ind_Caller_Number_2","Ind_RBT_2","Ind_Group_ID_2",
"Ind_Caller_Number_3","Ind_RBT_3","Ind_Group_ID_3",
"Ind_Caller_Number_4","Ind_RBT_4","Ind_Group_ID_4",
"Ind_Caller_Number_5","Ind_RBT_5","Ind_Group_ID_5",
"Ind_Caller_Number_6","Ind_RBT_6","Ind_Group_ID_6",
"Ind_Caller_Number_7","Ind_RBT_7","Ind_Group_ID_7",
"Ind_Caller_Number_8","Ind_RBT_8","Ind_Group_ID_8",
"Ind_Caller_Number_9","Ind_RBT_9","Ind_Group_ID_9",
"Ind_Caller_Number_10","Ind_RBT_10","Ind_Group_ID_10",
"Ind_Caller_Number_11","Ind_RBT_11","Ind_Group_ID_11",
"Ind_Caller_Number_12","Ind_RBT_12","Ind_Group_ID_12",
"Ind_Caller_Number_13","Ind_RBT_13","Ind_Group_ID_13",
"Ind_Caller_Number_14","Ind_RBT_14","Ind_Group_ID_14",
"Ind_Caller_Number_15","Ind_RBT_15","Ind_Group_ID_15",
"Ind_Caller_Number_16","Ind_RBT_16","Ind_Group_ID_16",
"Ind_Caller_Number_17","Ind_RBT_17","Ind_Group_ID_17",
"Ind_Caller_Number_18","Ind_RBT_18","Ind_Group_ID_18",
"Ind_Caller_Number_19","Ind_RBT_19","Ind_Group_ID_19",
"Ind_Caller_Number_20","Ind_RBT_20","Ind_Group_ID_20",
"Ind_Caller_Number_21","Ind_RBT_21","Ind_Group_ID_21",
"Ind_Caller_Number_22","Ind_RBT_22","Ind_Group_ID_22",
"Ind_Caller_Number_23","Ind_RBT_23","Ind_Group_ID_23",
"Ind_Caller_Number_24","Ind_RBT_24","Ind_Group_ID_24",
"Ind_Caller_Number_25","Ind_RBT_25","Ind_Group_ID_25" };
数组中有这么多的字段。我想知道怎么做能让我第一次或许更新前10个，第二次更新后10个，以及如何判断更新到那个子段了，并且知道更新了多少个字段。必须是这个数组。因为这是一个接口，我什么都改不了的。大家帮帮我啊。50分给解决问题的人

定义几个static的标志字段用于记录位置，个数等

[边城狂人]

设置一个变量，保存当前更新到的 index
比如
String[] test = new String[50];
int index = 0;

for (int i = index; i < 10; ++i, ++index) {
test[i] = "a";
}

for (int i = index; i < 10; ++i, ++index) {
test[i] = "b";
}

[alaal]

或者定义一个和array内容一样的list，

通过比较每一个位置的元素，知道哪个没有被更新

[feijipaopao]

设置一个变量，保存当前更新到的 index
比如
String[] test = new String[50];
int index = 0;

for (int i = index; i < 10; ++i, ++index) {
test[i] = "a";
}

for (int i = index; i < 10; ++i, ++index) {
test[i] = "b";
}

能这么用吗？能不能给再细一些，该怎么用呢

[lulesheng1983]

应该吧index定已成static

[lulesheng1983]

static int index=0;
下次负值就可以记住起始位置了

[feijipaopao]

哦，明白了。

[边城狂人]

不需要定义成 static 的，关键是看在什么地方定义。
一般情况做，定义为一个类的成员可能会比定义为 static 的要好。
编程的时候要尽量少定义 static 的变量。

[feijipaopao]

有没有使用过的代码给我看看，让我能够明白一些呢

[feijipaopao]

我该如何知道这些数组那些是被更新了。那些是没有被更新的呢？

[LDH202]

限制的这么严格。。。。。

那只好生成另一个一模一样的数组，然后调用循环来判断了。

当然也可以记录其地址，因为基本上每个字符串都有不同的地址

[feijipaopao]

是啊。现在每次更新数组都要计算更新了那些。可是我没有好的思路。大家给出出主意。

[feijipaopao]

谁还有办法？

[边城狂人]

设置一个一样大小的标志数组，boolean 型的，然后在这个标志数组里做标记
