Create a Java project called 5 and a class named 5
Create a second new class named CoinFlipper
1. Add 2 int instance variables named headsCount and tailsCount
2. Add a constructor with no parameters that sets both instance variables to 0;
3. Add a public int method named flipCoin (no parameters). It should generate a random number between 0 & 1 and return that number. (Important note: put the Random randomNumbers = new Random(); statement before all the methods, just under the instance variables.)
4. Add a public void method named countFlips (no parameters) that will use a loop to call flipCoin 100 times and look at its result. It should count how many times the flip is heads (1) and how many times it’s tails (0) and put those values into the instance variables, headsCount and tailsCount
5. Write a public String method named toString that will return a string containing the instance variables along with a label for each one.
Back in the 5 class:
1. Declare and instantiate a CoinFlipper object named flippy (no parameters).
2. Call countFlips for flippy
3. Use the toString method to print flippy’s data.
4. Debug and test your program. Run it several times to see how the number of heads and tails compare.

Expert Solution

Code

Now here you can not give class name 5 only number so i just named Class5

import java.util.Random;

class CoinFlipper
{
private int headsCount;
private int tailsCount;
Random randomNumbers = new Random();
public CoinFlipper() {
headsCount=0;
tailsCount=0;
}

public int flipCoin()
{
return randomNumbers.nextInt(2);
}

public void countFlips()
{
for(int i=0;i<100;i++)
{
if(flipCoin()==1)
headsCount++;
else
tailsCount++;
}
}

@Override
public String toString() {
return "Heads Count: " + headsCount + ", Tails Count:" + tailsCount ;
}

}
public class Class5 {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
CoinFlipper coinObj=new CoinFlipper();
coinObj.countFlips();
System.out.println(coinObj);
}

}
output
