can u give me this program

[Gopi @ IBM Bangalore Manyata]

hi i am new to java
i have one question
if i want to write a program for Bank

here all inputs i should give runtime only(so i have to use Scanner )
first it should ask do u want to open a bank account
banks are two types national and international
it should ask which type of bank u need to open and for national banks
min balance is 10000 and for national its 5000
after that it should choose for bank and then it ask for money

Is this homework? What code have you written so far?

Is this homework? What code have you written so far?

I'm thinking it's more likely that Gopi took on a job at IBM Bangalore as a
Java programmer, and now has to speedily and desperately learn the language.

this is my code but getting some mistakes

my code is like this

[hundreds of lines of code omitted]

this is my code but getting some mistakes

It's not realistic to expect people to debug hundreds of lines of
ill-formatted, repetitive code with little or no indication of what's
wrong. Consider creating a much shorter example that demonstrates the
problem, as discussed here: <http://sscce.org/>

For the particular case of IndexOutOfBoundsException arising in
subclasses of Bank, note that ArrayList indexes start at zero, not one.

my code is like this

[hundreds of lines of code omitted]

this is my code but getting some mistakes

For the particular case of IndexOutOfBoundsException arising in
subclasses of Bank, note that ArrayList indexes start at zero, not one.

<http://download.oracle.com/javase/6/docs/api/java/util/ArrayList.html>

For the general case, do not use TAB characters to indent Usenet posts. Do
use spaces, up to four per indent level.

In the particular case of (TABs removed):

public class Bank {
String AccID;

ArrayList<Bank> national;
ArrayList<Bank> privte;

public String getCustomerID(String bankName,String accType )
{

String randomString;
Random randomGenerator = new Random();
int randomInt=randomGenerator.nextInt();
randomString=Integer.toString(randomInt);
AccID=bankName.concat(randomString);

return AccID;
}
}

You should not allocate a new 'Random' with each call. Make the generator a
member of the class. Otherwise the "random" sequence starts over with each call.

The 'AccID' variable, on the other hand (OTOH), should NOT be a member
variable - as is, it will be shared by every caller to the same object's
'getCustomerID' method. Also, variable names should start with a lower-case
letter, with one exception that does not apply here. Read the coding
conventions document:
<http://www.oracle.com/technetwork/java/codeconv-138413.html>

Finally, learn to spell "you" and "I". Be professional.

if i want to write a program for Bank

No you don't. No bank would use a program that simplistic.
