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
}
}
}
