#
# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
#

# Senior Engineer Test
### **Develop a service that simulates basic banking operations in a programming language of your choice. This service will manage accounts, process deposits, withdrawals, and transfers between accounts.**
### The system should be designed reflecting real-world constraints of a bank.
## Requirements:
1. A class or set of functions that allow:
* Account creation: Allow users to create an account with an initial deposit.
* Deposit: Enable users to deposit money into their account.
* Withdrawal: Allow users to withdraw money from their account, ensuring that overdrafts are not allowed.
* Transfer: Enable transferring funds between accounts.
* Account balance: Provide the ability to check the account balance.
2. Database:
* In-memory data storage will suffice, no need to have a database alongside the project, but you can add one at your discretion
The word “service” here is used in a “software component/module” rather “deployable unit with an API” sense, no need to provide API for it.
## Feel free to take as along as you need to complete the exercise. This will be used as a base for a follow-up pair programming session.
