Question
(I need complete java program, not uml thanks)
Draw UML class diagram to show the relationships between bank, customers, and accounts. Customers may have more than one account and these accounts are saving account and checking account. Each customer’s account has current balance it is based on deposit and withdrawal activities. The balance of the bank account must never go below zero. A savings account gain interest. The bank permits customers to store money in a savings account and, on a monthly basis, the savings account will accumulate based on the following formula:
balance = balance + (interest rate x balance)
A checking account enables the customer to make any number of deposits and withdrawals. To protect their customers, the bank will permit a fixed amount of overdraft protection. This protection enables the customer’s balance to drop below zero, but not below the amount of overdraft protection. The account’s overdraft amount is decremented as it is used Based on the UML diagram, develop a complete program to solve the problem.

}
public BankAccount()
{

savingsBalance = 0;
interest = 0;
}
public BankAccount(String cusName,int cusId,String aType)
{

}
}
else{

System.out.println("Insufficient Balance");
System.exit(0);
}
else{

}
}
}
public void addInterest()
{

}

{

{

}
public void display(){
if(accountType=="savings"){

System.out.println("Customer Name= "+custName+" CustomerId="+custID+" BankAccount Type ="+accountType+" Available Balance="+savingsBalance);
}
else{
addOverdraft();
System.out.println("Customer Name= "+custName+" CustomerId="+custID+" BankAccount Type ="+accountType+" Available Balance="+currentBalance);
}
}
}
class Ideone
{
public static void main (String[] args) throws java.lang.Exception
{
BankAccount account = new BankAccount("Jimmy",1234,"checking");
account.setValues();
account.withdraw(250);
