java笔记--if的使用

    public static void main(String[] args) {
        //if的使用
        /*int week=0;
        
        if(week==1)
            System.out.println(week+"对应中文是星期一");
        else if(week==2)
            System.out.println(week+"对应中文是星期二");
        else if(week==3)
            System.out.println(week+"对应中文是星期三");
        else if(week==4)
            System.out.println(week+"对应中文是星期四");
        else if(week==5)
            System.out.println(week+"对应中文是星期五");
        else if(week==6)
            System.out.println(week+"对应中文是星期六");        
        else if(week==7)
            System.out.println(week+"对应中文是星期七");
        else
            System.out.println(week+"无对应星期");*/
        //while累加思想
        /*int x=1;
        int sum=0;
        while(x<=10){
            sum=sum+x;
            x++;
        }
        System.out.println("sum="+sum);*/
        /*计算器思想
         练习：
         1~100之间 6的倍数出现的次数    可用for替换
         */
        int x=0;
        int count=0;
        while(x<=100){
            if(x%6==0)
                count++;
                System.out.println("x="+x);
            x++;
        }
        System.out.println("count="+count);
    }
