C语言训练-求素数问题 （Java代码）

参考代码:

import java.util.Scanner;

public class Main1139 {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int x = sc.nextInt();

for (int i = 2; i <= x; i++) {

if (i == 2)

System.out.print(i + " ");

for (int j = 2; j < i; j++) {

if (i % j == 0)

break;

if (j == i - 1)

System.out.print(i + " ");

}

}

}

}
