java - Random Coin Flipper output number of times run -
i attempting write program in java flips imaginary coin , outputs flips , when side has been flipped 3 times, stops , tells number of times flipped. program doesn't seem working
my code below:
import java.util.*; public class flipperthree { public static void main(string[] args) { boolean fin = false; while(!fin){ system.out.println("welcome flipper!"); int h = 0; int hcount = 0; int tcount = 0; int ocount = 0; string random; string[] ht; boolean done = false; while(!done){ for(hcount<3||tcount<3){ht = new string[] {"heads","tails"}; random r =new random(); random = ht[r.nextint(ht.length)]; system.out.println(random); } if (hcount!=3||tcount!=3){ if(random == ht[h]){ hcount++; ocount++; tcount = 0; }else{ hcount = 0; tcount++; ocount++; } }else{ system.out.println("bingo!that took " + ocount+" flips 3 in row!"); done = true; } } }fin = true; } }
in general program more complicated necessary. need single loop
you using
==compare strings. instead ofrandom == ht[h]shouldrandom.equals(ht[h])instead of looping while either heads or tail counts less 3, want keep looping while both less three. instead of
hcount!=3 || tcount!=3it'shcount!=3 && tcount!=3
.
public class flipperthree { public static void main(string[] args) { system.out.println("welcome flipper!"); int h = 0; int hcount = 0; int tcount = 0; int ocount = 0; string[] ht = new string[] {"heads","tails"}; random r =new random(); while (hcount < 3 && tcount < 3) { string random = ht[r.nextint(ht.length)]; system.out.println(random); if(random.equals(ht[h])){ hcount++; ocount++; tcount = 0; } else{ hcount = 0; tcount++; ocount++; } } system.out.println("bingo!that took " + ocount+" flips 3 in row!"); } } $ java flipperthree welcome flipper! tails heads heads tails heads heads tails tails tails bingo!that took 9 flips 3 in row!
