Storing object in concurrenthashmap created using constructor - object

This is my code. Am trying to add employees dynamically to the concurrenthashmap. There is no error but i get inputMismatchException. Experts, please help.
CODE:
try {
System.out.println("No of employees: ");
int count = userdata.nextInt();
System.out.println("count: " + count);
System.out.println("enter employee details.");
// with ConcurrentHashMap
ConcurrentHashMap<Integer, employee> employeeDetails = new ConcurrentHashMap<>();
int index = 0;
do {
employeeDetails.put(index, new employee(userdata.nextInt(), userdata.nextLine(), userdata.nextLine()));
index++;
count--;
} while (count != 0);
System.out.println(employeeDetails.toString());
System.out.println("enter item to remove: ");
String removeValue = userdata.nextLine();
employeeDetails.forEach((k, v) -> {
if (v.equals(removeValue)) {
employeeDetails.remove(k);
}
});
System.out.println("afer removal: \n" + employeeDetails.toString());
} catch (Exception e) {

Transaction Module for a Banking app - Is Answered

I need help in Transaction Class:
The transaction class with contain the following data:
A counter to track the number of transactions. Increment for every deposit or
withdrawal made. A customer is allowed to make up to 5 transactions on a single login.
o A history of the 5 possible transactions. This will be an array of dollar amounts where a
negative amount is a withdrawal and a positive number is a deposit. Clear the history
each time a customer logs in.
Transaction objects will perform the following:
o Update history to reflect any transaction made when a user is logged in. Keep track of
each transaction value made as described above in the transaction data section. After
each transaction, increment the transaction counter.
o Clear history of all amounts stored and reset the transaction count

Some code from Account Class
public double getBalance()
{
return customerBalance;
}
public void Customerdeposit()
{
double deposit = Convert.ToDouble(Console.ReadLine());
if (deposit <= 0)
{
Console.WriteLine("\nCannot Deposit");
}
else
{
customerBalance = customerBalance + deposit;
}
}
public void customerWithdraw()
{
double withdraw = Convert.ToDouble(Console.ReadLine());
{
if (withdraw >= 0)
{
customerBalance = customerBalance - withdraw;
}
else
{
Console.WriteLine("There is not Sufficient fund in your account to withdraw");
} }}}
I try to write code for transaction class using the code below
But there are many errors at obj.Customerdeposit(amount); in both if condition and at Update(amount);
class Transaction
{
private int[] arr;
private int cntr;
Transaction()
{
arr = new int[5];
cntr = 0;
}
private void update(int amount)
{
arr[cntr] = amount;
cntr++;
}
public void credit(Account obj, int amount)
{
if(cntr!=5)
{
obj.Customerdeposit(amount);
return;
Update(amount);
}
else
{
Console.WriteLine("Transaction limit exceeded");
}}
public void debit(Account obj, int amount)
{
if(cntr!=5)
{
obj.customerWithdraw(amount);
return;
Update(-amount);
}
else
{
Console.WriteLine("Transaction limit exceeded");
}
}
}
}

You have specified everything from attributes to functions, just write the code.
Now this will be spoonfeeding but then too, your changes are wrong.
Account Class:
public double getBalance()
{
return customerBalance;
}
public bool Customerdeposit()
{
double deposit = Convert.ToDouble(Console.ReadLine());
if (deposit <= 0)
{
return false;
}
customerBalance = customerBalance + deposit;
return true;
}
public bool customerWithdraw()
{
double withdraw = Convert.ToDouble(Console.ReadLine());
{
if (withdraw <= 0 || customerBalance < withdraw )
{
return false;
}
customerBalance = customerBalance - withdraw;
return true;
}
}
}
Now your TransactionClass can be: (add other functionalities yourself)
class Transaction
{
private int[] arr;
private int cntr;
Transaction()
{
arr = new int[5];
cntr = 0;
}
private void update(int amount)
{
arr[cntr]=amount;
cntr++;
}
public void credit(Account obj, int amount)
{
if(cntr!=5)
{
if(obj.CustomerDeposit(amount))
Update(amount); //works only when true returned from above.
else
//print message
}
else
Console.WriteLine("Transaction limit exceeded");
}
public void debit(Account obj, int amount)
{
if(cntr!=5)
{
if(obj.CustomerWithdraw(amount))
Update(-amount);
else
//print any message
}
else
Console.WriteLine("Transaction limit exceeded");
}
}
Call will be made for each transaction:
Transaction trans= new Transaction();
trans.credit(myCustAcc[user],500);

J2ME Login and Search Record Store

I'm new to J2ME and I'm taking a class where we use it. I created a simple travel reservation MIDlet using choice groups text fields etc. I then added a Record Store to capture this information. I now have a user login that only requires a user name, but i don't know how to verify that the user name is in the Record Store, so instead I accept any one as long as the Textfield for the user name is not empty. My first question is how would I verify that the user exist, I already can create an account. The second question is how can I search a record store not by id but say using a string within a certain range for each row of the Record store.
Here is my code so far:

not able to read J2ME PIM contact details

I want to read contact details like firstname , lastname, mobile no, telephone , fax, address, synchronization and UID details using PIM apis in Nokia S60 sdk.
But , I am getting only Contact.TEL and Contact.EMAIL value, none of the other values I am getting , although, I am able to see other fields like first name, last name in the emulator contact details.
I have configures all the required permission .
ContactList addressbook = (ContactList) (PIM.getInstance().openPIMList(
PIM.CONTACT_LIST, PIM.READ_ONLY));
Contact contact = null;
Enumeration items = addressbook.items();
while (items.hasMoreElements()) {
String name = "";
String telephone = "";
String mobile = "";
String email = "";
String InternetTelephone = "";
String Company = "";
String JobTitle = "";
String Synchronisation = "";
String UID = "";
String LastModified = "";
String contactRow = "";
System.out.println("\n *** NEW ITEM ***");
contact = (Contact) (items.nextElement());
System.out.println(" * contact : " + contact.toString());
try {
name = contact.getString(Contact.FORMATTED_NAME, 0);
System.out.println("Name = " + name);
} catch (Exception ex) {
System.out.println(" Name error "+ ex.getMessage());
}
try {
mobile = contact.getString(Contact.ATTR_MOBILE, 0);
System.out.println("Name = " + name);
} catch (Exception ex) {
System.out.println(" Name error "+ ex.getMessage());
}
try
{ telephone = contact.getString(Contact.TEL, 0);
System.out.println("Telephone = " + contact.getString(115, 0)); //field 115: Telephone
} catch (Exception ex) {
System.out.println(" Telephone error "+ ex.getMessage());
}
try
{
email = contact.getString(Contact.EMAIL, 0);
System.out.println("E-mail = " + contact.getString(103, 0));
} catch (Exception ex) {
System.out.println(" E-mail error "+ ex.getMessage());
}
try
{
UID = contact.getString(Contact.UID, 0);
System.out.println(" UID " + UID );
} catch (Exception ex) {
System.out.println(" UID error "+ ex.getMessage());
}
try
{
LastModified = contact.getString(114, 0);
System.out.println(" Last modified " + contact.getString(114, 0));
} catch (Exception ex) {
System.out.println(" Last modified error "+ ex.getMessage());
}
looking forward your valuable suggestions.
Thanks in advance.

rms queries, find a phrase inside a text

I want to do a midlet application for save product with its bar code, product's name, product's description and price. Then it is going to be saved as it:
123123123-coca cola-soda-6.50
124512341-crystal coca-soda-7.00
well for this I have built this code:
public boolean ProductoAgregar(String dato) // add product
{
byte bytes[] = dato.getBytes();
try {
rs.addRecord(bytes, 0, bytes.length);
return true;
} catch (RecordStoreException ex) {
ex.printStackTrace();
return false;
}
}
public boolean ProductoModificar(String dato, int id) // update product
{
try
{
byte bytes[] = dato.getBytes();
rs.setRecord(id, bytes, 0, dato.length());
return true;
}
catch(Exception ex)
{
return false;
}
}
public boolean ProductoEliminar(int id)// delete product
{
try
{
rs.deleteRecord(id);
return true;
}
catch(Exception ex)
{
return false;
}
}
I don't have an idea for how to create the method for find a product (with a part of its name, or with its bar code) and what is going to return? maybe an array?
For example all products has write coca in its name (or in description) or
find a unique product with bar code.
(This is a class with I'll instance for use its methods)

you can try following code, by editing as per your usage. I am using below code for searching an item from RMS Data.
public boolean SearchRecord(String Rec, int pos )
{
String [] data = getRecordData();
Rec = Rec.substring(0,pos);
for ( int i = 0 ; i < data.length ; i++ )
{
data[i] = data[i].substring(0, pos );
if ( Rec.toString().trim().equals(data[i].toString().trim()) )
{
data = null; // System.gc();
return true;
}
}
data = null; // System.gc();
return false;
}
By Changing the value of "pos" variable you can achieve your goal.
