How do I correctly use scopes?

So I am working on my first project- however, the compiled program 'skips' on some of the code I wrote because of the way I used the scope in it (I figured). Anyways, I will supply the code below.

import java.util.Random;    public class TicTacToe {      public static void main(String[] args){          Random placement = new Random();          int placement1 = placement.nextInt(3);          if (placement1 == 1){              for(int i = 0 ; i < 10000 ; i++){                  int placementi = placement.nextInt(3);                  if (placementi != 1 ){                      break;                  } else{                      placement1++;                  }              }          } else {              if(ticTacToe[0][placement1] == 1){                  for(int i = 0 ; i < 10000 ; i++){                      int placementx = placement.nextInt(3);                      if (placementx != 1 && placementx != placement1){                          break;                      } else{                          placement1++;                      }                  }                  ticTacToe[0][placement1] = 2;                  System.out.println(placement1);                  for(int i = 0 ; i < 3 ; i++){                      for(int j = 0 ; j < 3; j++) {                          System.out.print(ticTacToe[i][j] + " " );                      }                      System.out.println();                  }              }                }      }  }  

obviously, this is probably not the best way to execute this code however I am aiming to improve so giving your opinion can be helpful.
