Here is a simple Java program that implements the given scenario:

```java
import java.util.Scanner;

class Customer {
String name;
int aadharNo;
int productId;

Customer(String name, int aadharNo, int productId) {
this.name = name;
this.aadharNo = aadharNo;
this.productId = productId;
}
}

class CouponCustomer extends Customer {
CouponCustomer(String name, int aadharNo, int productId) {
super(name, aadharNo, productId);
}

void transaction() {
System.out.println(name + " " + aadharNo + " " + productId + " Amount = 0");
}
}

class NonCouponCustomer extends Customer {
int installmentNo;
int paidAmount;
int balanceAmount;

NonCouponCustomer(String name, int aadharNo, int productId, int installmentNo) {
super(name, aadharNo, productId);
this.installmentNo = installmentNo;
if (installmentNo == 1) {
this.paidAmount = 17000;
this.balanceAmount = 18000;
} else if (installmentNo == 2) {
this.paidAmount = 10000;
this.balanceAmount = 4000;
} else {
this.paidAmount = 8000;
this.balanceAmount = 4000;
}
}

void transaction() {
System.out.println(name + " " + aadharNo + " " + productId + " Paid amount = " + paidAmount + " Balance amount = " + balanceAmount);
}
}

public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter the option: ");
int option = sc.nextInt();
if (option == 1) {
System.out.println("Customer name: ");
String name = sc.next();
System.out.println("Aadhar name : ");
int aadharNo = sc.nextInt();
System.out.println("Product id: ");
int productId = sc.nextInt();
CouponCustomer cc = new CouponCustomer(name, aadharNo, productId);
cc.transaction();
} else if (option == 2) {
System.out.println("Customer name: ");
String name = sc.next();
System.out.println("Aadhar name : ");
int aadharNo = sc.nextInt();
System.out.println("Product id: ");
int productId = sc.nextInt();
System.out.println("Enter the installment number: ");
int installmentNo = sc.nextInt();
NonCouponCustomer ncc = new NonCouponCustomer(name, aadharNo, productId, installmentNo);
ncc.transaction();
} else {
System.out.println("Exit");
}
}
}
```

This program first asks for the option. If the option is 1, it creates a `CouponCustomer` and performs the transaction. If the option is 2, it creates a `NonCouponCustomer` and performs the transaction. If any other option is entered, it exits. The `transaction` method is overridden in both `CouponCustomer` and `NonCouponCustomer` classes to provide the specific implementation for each type of customer.
