I need to have the player enter the word Head or Tail instead of just 1 or 2, any idea anyone? how do i achieve this?

import java.io.IOException;
import java.io.InputStreamReader;
import java.io.BufferedReader;

public class Coin {
public static void main(String[] args) throws IOException {
String[] guess = { "head", "tail" };
String input = new String();
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

for(int round=1; ; round++) {
System.out.println("Round " + round);
System.out.println("Guess head or tail");
input = br.readLine();

int rand = (int)(Math.random()*2);

if(guess[rand].equals(input)) {
System.out.println("You win 10 points");
} else {
System.out.println("Computer win 10 points");
}
}
}
}

Due to this being a school assignment, the assignment does not allow us to use any loops but must use math.random to generate random numbers...any idea??

Even if you're not allowed to use loops (ugh, what sort of stupid assignment is this?) YUPAPA gave you all the information you need. Hint:
String[] guess = { "head", "tail" };

The only reason why loops may not because this assignment 2 and assignment 3 covers looping? ;)

Why do you bring your homework here?

What Exactly is this Code for? I need more detail before I can help.
