coin toss program(Eclipse)

[ccie007]

I am trying to write a program which tosses coin and shows "heads" and "tails".It will continue to show heads and tails randomly untill it shows "heads" 3 times consecutively.

Sample output should be like this:

heads
tails
heads
heads
tail
tail
heads
heads
heads.

I have almost written the program but can't figure out how stop with program when it shows "heads" 3 times consecutively.

My code at the moment(mind you I am using Eclipse):

import acm.program.*;
import acm.util.*;
import java.awt.*;



public class chapter6ques2 extends ConsoleProgram{


public void run(){


RandomGenerator rgen = new RandomGenerator();

int coinflip = rgen.nextBoolean() ? 0 : 0;


for(int i=1;coinflip<=3;++i){



if (rgen.nextBoolean()){


println("HEADS");
coinflip+=1;



}else{

coinflip-=1;

println("TAILS");




}


}
print(coinflip);
}
}

Do you have a design or algorithm to solve your problem?

Can you post the steps you want to take in the program to solve the problem?
Until you have a design for your code, its a waste of time to write code.

How about storing past results to the last 3 values using a collection. That way when all three results equal heads or tails then the program can be told to stop?

Suppose you haven't counted three consecutive 'head's yet and a 'tail' is thrown. No matter how many heads you counted before a tail should reset the number of consecutive heads to zero again. So the counting scheme runs as follows:

if (head) count++
else if (tail) count= 0
if (count == 3) ... // three consecutive heads counted

kind regards,

while (count < 3) {
    // do your stuff
}
