JAVA第六次作业

1.

public class Hestia {
    public static void main(String[] args) {

    int temp = 0; // 定义一个记录次数的变量

    for (int i = 1; i <= 100; i++) { // 利用 for 循环遍历 1-100 的数

        if (i % 3 == 0) { // 设置条件，能被 3 整除则输出

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

            temp++; // 迭代输出次数

        }

        if (temp == 5) { // 如果输出五次就退出循环

            break;

        }

    }

}
}
