Java Lotto / get random number example

This code was made in five minutes, so there are many weak point.

this code save that the number from 1 to 45 has been count N times.
finally, i will get 6 numbers.

import java.util.Random;

public class lottonamatja {
   public static void main(String[] args) {
      Random ranNum = new Random();    // random variable
      long[] cloneNum = new long[45]; 
      long[] num = new long[45];
      long[] lottoNum = new long[6];    // get real number(I wanted)
      long count = 1;
      long N = 100000000;
   
      for (long i = 0; i< N ; i++) {
         int tempRanNum = ranNum.nextInt(45)+1;    // random number of 1~45
         num[tempRanNum-1] += count;    // count of each number about N times
      }

//copy number
      cloneNum = num.clone();

// sorting count
      for (int i = 0; i < 45; i++) {
         for (int j = i + 1; j < 45; j++) {
            if (num[i] > num[j]) {
               long tmp = 0;
               tmp = num[i];
               num[i] = num[j];
               num[j] = tmp;
            }
         }
      }
   
// compare sorting number to original number ( this is real number(1~45), num[i] or cloneNum[j] is counting number)
      for (int i = 0 ; i < 6; i++) {
         for (int j = 0 ; j < 45; j++) {
            if (num[i] == cloneNum[j])
               lottoNum[i] = j+1;    // save result number 
         }
      }
   
// sorting about 6 number
      for (int i = 0; i < 6; i++) {
         for (int j = i + 1; j < 6; j++) {
            if (lottoNum[i] > lottoNum[j]) {
               long tmp = 0;
               tmp = lottoNum[i];
               lottoNum[i] = lottoNum[j];
               lottoNum[j] = tmp;
            }
         }
         System.out.print(lottoNum[i] + " ");    //i wanted to real number
      }
   }
