Lottery help, looping problem

[hadoken5]

I'm new to these forums :( So I don't know the format that I should be posting questions in so I'm sorry if I post incorrectly.

Anyway, I'm making a lottery program for class similar to lotto 6/49 in Ontario, Canada. So far I have made it so that you enter your numbers, you pick how many numbers you want it to match, and then it picks non-repeating numbers from 1-49 and compares them.

Now it doesn't really compare them the way I want it to. What's happening is that I will pick the numbers and what will happen is it will keep on looping and spit out sets of 6 random numbers and compare them, the problem is, is that the computer is comparing ALL the random numbers, even the ones from the previous sets of random numbers. For example I pick: 1,2,3,4,5,6 and want to match 3 numbers, so I press go. Now I can see in the system output that the draws are:
23
35
45
32
24
31

40
29
37
6
13
34

1
33
4
25
42
18


As you can see it is matching numbers from previous draws making all my draws take only a maximum of 5 sets to match which is unrealistic.

Here is my code for the loop:

  {
    if(e.getSource()==button1)
      for(int g=0;g<6;g++)
    {
      entries[g]=Integer.parseInt(t[g].getText());
    }
    numbertomatch=Integer.parseInt(matchnumber.getText());
    {
      while(numbertomatch>matches)
      {
        {
          for(int m=0;m<6;m++)
          {
            do
            {
              x=(int)(Math.random()*49)+1;
            }while(checklist[x]==1);
            
            d[m].setText(""+x); //placing RN into a Label
            draws[m]=x; //storing RN to appropriate
            checklist[x]=1;
            tries++;
            System.out.println(x);
            
            
            for(int q=0;q<6;q++)
            {
              for(int u=0;u<6;u++)
              {
                if(draws[u]==entries[q])
                {
                  matches++;
                }
              }
            }
            draws[m]=0;
            plays=new JLabel ("It took "+ tries +" plays to match.");
          }
        }
      }
    }
  }

I also wanted it to count how many times it took to match the numbers so I used the variable "tries" to count that, but it isn't counting. I think the problems are related. Any help is welcome, and here is my entire code if you'd like to try it out.

Come on, help please? :(

[hadoken5]

Ok I figured out that I need to set matches to 0 before every loop to solve my problem. My only problem now is that I don't know how to reset checklist without breaking its function, which is to prevent the random number from repeating. I don't know if this forum is dead but anyone out the help me please :(
