1.假如还有59天放假,问有多少个星期零多少天?
public class Change{
public static void main(String[] args){
int n = 59;
int week = 59 / 7;
int day = 59 % 7;
System.out.println("一共有" + week + "周");
System.out.println("剩余天数:" + day + "天");
}
}
2.定义一个变量保存华氏温度,华氏温度转摄氏度的公式为:5/9*(华氏温度-100),请求出华氏温度对应的摄氏温度。234.6
public class Change{
public static void main(String[] args){
int n = 59;
int week = 59 / 7;
int day = 59 % 7;
System.out.println("一共有" + week + "周");
System.out.println("剩余天数:" + day + "天");
System.out.println("%%%%%%%%%%%%%%%" );
double temperatureofhuashi = 234.6;
double temperature = 5.0 / 9*(temperatureofhuashi-100);//要考虑数学公式和java语言的特性,5--->5.0,
// 5/9的话结果是0.在进行后面的运算就都是0了。
System.out.println("真正的摄氏度:" + temperature);
}
}
体验编程的乐趣哈?
