Here is a simple Java program that creates a BankAccount class and uses an array of objects to create 5 customers. It also includes methods for credit, debit, and displaying the balance.

```java
class BankAccount {
String name;
String accountType;
int accountNumber;
double balance;

BankAccount(String name, String accountType, int accountNumber, double balance) {
this.name = name;
this.accountType = accountType;
this.accountNumber = accountNumber;
this.balance = balance;
}

void credit(double amount) {
balance += amount;
}

void debit(double amount) {
if (balance = amount) {
balance -= amount;
} else {
System.out.println("Insufficient balance");
}
}

void display() {
System.out.println(name + " " + accountType + " " + accountNumber + " " + balance);
}
}

public class Main {
public static void main(String[] args) {
BankAccount[] customers = new BankAccount[5];
customers[0] = new BankAccount("Reena", "Savings", 123, 1000);
customers[1] = new BankAccount("Robin", "Current", 456, 2000);
customers[2] = new BankAccount("Praveen", "Savings", 789, 3000);
customers[3] = new BankAccount("Sherin", "Current", 234, 2500);
customers[4] = new BankAccount("Deena", "Savings", 567, 2000);

// Perform credit, debit and display operations here
// For example, to credit 1000 to Reena's account:
customers[0].credit(1000);
customers[0].display();
}
}
```

This program creates a BankAccount class with fields for the name, account type, account number, and balance. The BankAccount constructor initializes these fields. The credit method adds an amount to the balance, the debit method subtracts an amount from the balance if there are sufficient funds, and the display method prints the account details.

In the main method, an array of BankAccount objects is created and initialized with 5 customers. The credit method is then called on the first customer (Reena) to add 1000 to her balance, and her account details are printed.

Please note that this is a simple program and does not include user input or error checking. In a real-world application, you would want to include these features and also protect the account details with appropriate access modifiers and methods.
