Java 0-100素数

public class SuShu1 {
          public static void main(String[] args) {
              for (int i = 2; i <= 100; i++) {
                  boolean sushu = true;
                  for (int j = 2; j < i; j++) {
                      if (i % j == 0) {
                          sushu = false;
                          break;
                      }
                  }
                  if(sushu) {//是素数
                      System.out.println(i);
                  }
              }
          }
      }

升级版：

public class SuShu2{
    public static void main(String[] args){
        int count =0;
        for(int i=2;i<=10000;i++){
            boolean sushu=true;
            for(int j=2;j<i;j++){
                if(i%j==0){
                    sushu=false;
                }
            }
            if(sushu){
                System.out.println(i);
                count++;
                if(count%8==0){
                //每八个数字换一行
                    System.out.println();
                }
            }
        }
    }
}
