Question

Java programming.
*******I Need complete the following requirements in this project:
1/ Remove the applyRandomBonus method from the test class
2/ Create a File, Printwriter for an output file yourlastnameErrorLog.txt
3/ Set your maximum array size for accounts to 10
4/ Catch InputMismatch and ArrayIndexOutOfBounds exceptions when reading data from the file:
a. Skip any lines that cause an exception
b. Write information about the exception to the log file, yourlastnameError.txt
c. Include exception type and line number in exception message to your log file.
Example:
Data   Input   Mismatch   line:3   line   skipped
d. Continue processing the file
5/ Add Account Processing for the user to deposit or withdraw from an account:
a. Ask the user if they would like to process account(s)
b. Ask the user for account number
c. Search for account (using a separate method for your linear search), print and
error if account not found to the screen and to the log file,
yourlastnameError.txt.
d. Include account number and a message account not found to the log file print,
example:
Account   number   searched for not found: 555555
e. Once account is found, send it to a separate method that will handle
withdrawals and deposits. Ask the user if they would like to Deposit, Withdraw
or Exit. Print an error message to the screen and to the log file if the deposit or
withdrawal did not go through (see requirements from Phase 1). Include
account number of unsuccessful action, and the action (withdrawal, deposit) to
your error message, example:
Insufficient   funds   for   withdrawal:   5023742 balance:   540.0
f. Once the user is done with deposits/withdrawals for an account, loop around
and ask again if they’d like to process another account.
6/ All requirements from Final Phase 1 are required in this project, except for the
appyRandomBonus method and method call.

public class Account {
private long accountNumber;
private String firstName;
private String lastName;
private double balance;
// constructor
public Account(long accountNumber, String firstName, String lastName, double balance) {

public void setLastName(String lastName) {

}

public double getBalance() {

}

// deposit
public boolean deposit(double amount) {
boolean isDeposit = false;
if(amount>10 && amount <200) {
this.balance +=amount;
isDeposit = true;
}

return isDeposit;
}

public boolean withdraw(double amount) {
boolean isWithdraw = false;

if(amount>=10 && this.balance>=10) {
this.balance-=amount;
isWithdraw = true;
}
return isWithdraw;
}

// toString method is used to return current object data in the form of string
@Override
public String toString() {
return "Account{" +
"accountNumber=" + accountNumber +
", firstName='" + firstName + '\'' +
", lastName='" + lastName + '\'' +
", balance=" + balance +
'}';
}
}
