Please write junit test for the generateRandomValues(),canBet() and addMoney() that will include @Before annotation and methods: assertEquals, assertTrue, and assertFalse.

Thank you

The code:

import java.util.*;

import java.io.*;

import java.util.concurrent.ThreadLocalRandom;

interface IRandomValueGeneratorInterface {

// function defined in interface to generate random values in between l and r range

int generateRandomValues(int l, int r);

}

public class Main implements IRandomValueGeneratorInterface {

// data variable minB, declared inorder to store the minimum balance

double minB;

double currentBalance;

// constructor defined with two parameters, one minBalance and other instance of interface defined

Main(double minBalance) {

minB = minBalance;

}

// function defined in interface to generate random values in between l and r range

public int generateRandomValues(int l, int r) {

return ThreadLocalRandom.current().nextInt(l, r+1);

}

// funtion defined to get the input of current balance from user

double getCurrentBalance() {

Scanner scn = new Scanner(System.in);

System.out.print(" Enter Current Balance: ");

double x = scn.nextDouble();

currentBalance = x;

System.out.println("Current Balance is: " + currentBalance);

return x;

}

// function defined to check if user can bet with given amount

boolean canBet(double amnt) {

if(currentBalance - amnt >= minB) {

return true;

}

return false;

}

// function defined to add money to Balance

void addMoney(double amnt) {

// amount must be positve, then only add it to current balance

if(amnt >= 0) {

currentBalance+=amnt;

}

System.out.println("Current Balance is: " + currentBalance);

}

// function defined to bet on a number in range

void betOnANumber(double amnt, int min, int max, int selectedNumber) {

System.out.println(" You Won!");

int range = max - min + 1;

currentBalance += (range - 1) * amnt;

System.out.println("Current Balance is: " + currentBalance);

}

// else lose

else {

System.out.println(" You Lose");

currentBalance -= amnt;

System.out.println("Current Balance is: " + currentBalance);

}

}

else {

System.out.println("User can't Bet with this amount on number.");

}

}

// function defined to implement betting on probability

void betOnProbability(double amnt, double p) {

// checking if user can bet or not

if(canBet(amnt)) {

// we are taking here if probability is > 70% then win

if(p > 0.7) {

}

// else lose

else {

currentBalance -= amnt;

System.out.println("Current Balance is: " + currentBalance);

}

}

else {

System.out.println(" User can't Bet with this amount on probability.");

}

}

// Main method

public static void main(String[] args) {

// creating objects to implement the function defined

Main obj1 = new Main(-1050.6);

// getting the current balance from User

obj1.getCurrentBalance();

// adding money to balance

obj1.addMoney(5000.0);

// checking if he can bet with current balance for some amount

if(obj1.canBet(5000.0))

System.out.println(" yes you can bet");

else

System.out.println(" No you cannot bet");

// betting with amount

obj1.betOnANumber(5000, 1, 100, 36); // that user is betting on 34 in range [1,100]

// betting on probability

obj1.betOnProbability(5000, 0.8);

}
