Question

用java编程实现：产生一个1-12的数，并根据随机数的值输出对应月份的名称

Answer 1

public String getMonthName() {
int month = (int) (Math.random() * 12 + 1);
switch (month) {
case 1:
return "一月";
case 2:
return "二月";
case 3:
return "三月";
case 4:
return "四月";
case 5:
return "五月";
case 6:
return "六月";
case 7:
return "七月";
case 8:
return "八月";
case 9:
return "九月";
case 10:
return "十月";
case 11:
return "十一月";
default:
return "十二月";
}
}
PS: 是不是作业，上学要好好上呀，不能老指望别人，你学软件学费挺贵的吧！

Answer 2

Random rd = new Random();
int month = rd.nextInt(12)+1;
System.out.println("本月是："+month+"月")
这个是基本的思想代码 你参考参考。。

Answer 3

package ruang162p60.pkg2.pkg6.jiu93;
public class JiuP93 {
public static void main(String[] args) {
int a=(int)(Math.random()*12+1);
System.out.print("get a member is:"+a);
System.out.print("\n");
switch (a){
case 1: System.out.print("1 yuefen;");
break;
case 2: System.out.print("2 yuefen;");
break;
case 3: System.out.print("3 yuefen;");
break;
case 4: System.out.print("4 yuefen;");
break;
case 5: System.out.print("5 yuefen;");
break;
case 6: System.out.print("6 yuefen;");
break;
case 7: System.out.print("7 yuefen;");
break;
case 8: System.out.print("8 yuefen;");
break;
case 9: System.out.print("9 yuefen;");
break;
case 10: System.out.print("10 yuefen;");
break;
case 11: System.out.print("11 yuefen;");
break;
case 12: System.out.print("12 yuefen;");
break;
}
}
}

Answer 4
