Question

Here’s my import statement:

import java.util.*;

Here it is in main:

    Random Rand = new Random() ; 

Here it is in a public void method :

            int a = 0 ; 
            while (!done) 
        { 
            int a = Rand.nextInt(10) ;
            if (debug) stuff ; 
            if (possibles[a]==1) done = true ; 
        } 

Here’s the error message i get:

    TicTacToe.java:85: cannot find symbol
    symbol  : method nextInt(int)
    location: class Rand
                a = Rand.nextInt(10) ;
                        ^

Whats going wrong here? it seems like i’ve done everything right to me.

Answer 1

You defined Rand in the main method and tried to use it on your public void method. It is out of scope.

Try defining Rand in the same method ( and use lowercase this time)

Something like:

in main:

Random Rand = new Random();

In your method:

        Random rand = new Random();
        int a = 0 ; 
        while (!done) { 
            int a = rand.nextInt(10) ; //<-- the one declared above
            if (debug){ stuff ; }
            if (possibles[a]==1){ done = true ; } 
        }

BTW use braces always even in 1 line if’s
