Hi,
I have a question, somebody please help me:
I have a vector which will keep all the names the user typed in. Then the
user supposes can do a query like "give me all the name which starts with
'C'". In order to do that, I do something like this:
...
String[] array1 = new String[myVector.size()];
String tempString = "";
int j=0;
for (int i=0; i<myVector.size(); i++)
{
tmpString = (String)myVector.get(i);
if (tmpString.indexOf('C') != -1)
{
array1[j] = tmpString;
j++;
}
}
//since array1 may not be filled up with data, I transfer it to another
String array so I know how many element in the array
String array2 = new String[j];
for (int i=0; i<j; i++)
{
array2[i] = array1[i];
}
// then I will do display. Supposedly, say, array2.length is 20, if the user
wants to display first 5, I will display only the first 5 records, if the
user wants to display 30, and I will display 20 instead.
...
I can display all the situations ok except when myVector contains the names
that all start with "C" (which means array2.length should be
myVector.size()). then the program will crash. I think it might be array
out of bound problem, but I don't know how to fix it. Please help me.
