Java Library

Question

Hey guys,
I'm working on a guess my number program and I need to create a library which contains a method which will then be used by main to pick a secret random number.
I've created the library but when I compile everything and test it out (from my main method), I get compile errors.
I'm only going to be calling GuessMyNumber() for now with this program
Did I use it correctly? I'm trying to make it pick a random number from 1 to 1000
package library;
public class Gamble
        // returns either "heads" or "tails"
    public static String flipCoin( )
        int flipCode = (int)(2*Math.random()); // picks a 0 or a 1
        if(flipCode==0)
            return "heads";
        else
            return "tails";
    // returns 1, 2, 3, 4, 5, or 6
    public static int rollDie()
        int dieRoll = (int)(Math.random()*6)+1;
        return dieRoll;
    // Randomly picks number from 1 to 1000.
    public static int pickNumber(int 1, int 1000)
        int randomNumber = (int)(Math.random());
        return randomNumber;
}compile errors:
Gamble.java:32: <identifier> expected
     public static int pickNumber(int 1, int 1000)
     ^
Gamble.java:32: ';' expected
     public static int pickNumber(int 1, int 1000)
     ^

     ^

     public static int pickNumber(int 1, int 1000)
     ^

     ^
Gamble.java:35: <identifier> expected
          int randomNumber = (int)(Math.random());
          ^
Gamble.java:37: illegal start of type
          return randomNumber;
          ^
Gamble.java:37: ';' expected
          return randomNumber;
          ^
Gamble.java:41: class, interface, or enum expected
^
10 errors

Answer 1

The program is running but its running incorrectly.
Here is the loop. Should there be a specific order in which I should place each if statement? It doesn't seem to be working and I'm not sure how to make it right.
boolean userWon = false; // Haven't one yet.
        int guessCount = 0;
        while(!userWon) // Keeps going while userWon not true
            System.out.println("What is your first guess?");
            int userGuess = scan.nextInt();
            int computerNumber = Gamble.pickNumber(); // Main calling class method
            if(userGuess < computerNumber)
                System.out.println("That's too low!.");
            else
                System.out.println("That's too high!");
            if(userGuess == computerNumber)
                System.out.println("You got it in " + guessCount+ " guesses!  My number was " + computerNumber);
                userWon = true;
            else if(guessCount==9)
                System.out.println("You didn't get the number in 10 guesses.");
                System.out.println("You lose.  My number was " + computerNumber + ".");
                userWon=true;
            guessCount++;
    }Here is a test run:
----jGRASP exec: java GuessMyNumber
I've picked a secret number
It's between 1 and 1000
You get 10 guesses, try to guess it!
What is your first guess?
500
That's too low!.
What is your first guess?
400
That's too low!.
What is your first guess?
600
That's too low!.
What is your first guess?
800
That's too high!
What is your first guess?
700
That's too high!
What is your first guess?
600
That's too high!
What is your first guess?
500
That's too low!.
What is your first guess?
550
That's too low!.
What is your first guess?
560
That's too high!
What is your first guess?
557
That's too high!
You didn't get the number in 10 guesses.
You lose. My number was 299.
----jGRASP: operation complete.
What should I change around to make it work? :3
Thanks for all the help so far!
