JAVA CODE CLARIFICATION
Here is my script that works. I need to have the numbers, when generated, not be duplicated. I understand that I should use an array, but I do not know how. Some clarification would be appreciated. Thank you.
import java.util.Random;
public class Math
{
public static void main ( String args[] )
{
Random randomNumbers = new Random();
int number;
for ( int counter = 1; counter <= 30; counter++)
{
number = 1 + randomNumbers.nextInt( 49 );
System.out.printf("%d ", number);
if ( counter % 6 == 0 )
System.out.println();
}
}
}

When running the code I get the following error:
incompatible types
found: int[]
required: boolean[]
boolean[] oldnums = new int[50];
I know that the boolean will need to be changed to a string and I have looked on the internet for possible solutions but I do not understand their reasoning. I found this: String myString = Integer.toString(my int value).

Receiving the error: variable number might not have been initialized
while(oldnums[number]){num
the error happens under the [number] in the code.
Since the number has been intialized as an int number in the above code I do not know whyI am getting this.

This still does not work. I am going to try a different method - maybe two arrays instead of one.
Consider this closed.
Thanks for your help.

Thank you for your help. This is getting too complicated for me to understand so I am going to try something else. It was suggested utilizing two arrays instead of one so I will try that,

I also tried running the new code and it does not work so I know things are missing. Can you point me in the right direction, please. Thanks
