Array question

[Mike2020]

Hi all,

I try to expand my array by doing this.

for(int x=0; x < account.length;x++)
{ //System.out.println("in For loop,AccountNumber:"+ account[x].getAccountNumber());
int anumber = account[x].getAccountNumber();
if(anumber == Anums)
{ Match = "true";
aindex = x;
break;}
}
if(Match == "true")
{
int testnum = 500;
int testbalance = account[aindex].getBalance();
int finalbalance = testbalance + testnum;
account[aindex].setBalance(finalbalance);
//System.out.println("Account NO: " + account[aindex].getAccountNumber() + "-- Balance:" + account[aindex].getBalance());
}
else
{
int Len = account.length;
int newLen = Len + 1;
Account[] newArray = new Account[newLen];
System.arraycopy(account, 0, newArray, 0,Len);
account = newArray;
//account = Arraysize.arrayExpand(account);
int iindex = account.length;
int ibal = 0;
System.out.println("AccountLength:"+ iindex);
account[iindex] = new Account(Anums, ibal);
// String aM = "false";
// vMutex.addElement(aM);

}

I encounter this error.
java.lang.ArrayIndexOutOfBoundsExpection: 7 at ATM.run(ATM.java: 157)
The line 157 is: account[iindex] = new Account(Anums, ibal);

Do you know where I do wrong?

Thanks....

Mike

ArrayIndexOutOfBounds exception means that you have specified an index that is larger or equal to the length of the array, since arrays are 0-indexed. Replace the line with

account[iindex[red]-1[/red]] = new Account(Anums, ibal);

since iindex is defined to be the length.

Hi chessbot:

Hey, thank you so much, you are correct,
I just forget about that.

Thank you so much...
