Question

public class Main {

public static void main(String[] args) {
    // TODO Auto-generated method stub

    System.out.println("********WELCOME TO CUSTOMER DETAIL**********");
    System.out.println("");
    BankAccount customerDetails = new BankAccount();
    customerDetails.setAccountNumber(527553054);
    System.out.println("Account Number : " + customerDetails.getAccountNumber());
    customerDetails.setBalance(300000.00);
    System.out.println("Balance : " + customerDetails.getBalance());
    customerDetails.setCustomerName("Anish Shrestha");
    System.out.println("Customer Name : " + customerDetails.getCustomerName());
    customerDetails.setEmail("blah@gmail.com");
    System.out.println("Email : " + customerDetails.getEmail());
    customerDetails.setPhoneNumber(980709277);

I have copy-paste your code, there is no problem. In comment, the output:

      BankAccount deposit = new BankAccount(); 
      deposit.depositFunds(100); // The total sum of money : 100.0
      deposit.depositFunds(100); // The total sum of money : 200.0

      System.out.println(deposit.getBalance()); // 200.0
