请教这一段代码哪里出现错误了？

Question

完全按照书上敲的，本意是根据随机生成数输出今天是星期几的程序，书上的意思是为该类设计一个private的默认构造函数，这样可以避免给该类生成对象。（在某些情况下不需要生成对象，只把它当成公共程序），正常情况下这个程序应该显示DayOfweek() has private access in DayOfWeek
而我的程序显示的是Application0510201.java:4: invalid method declaration; return type required
    private DayOfWeek(){
            ^
Application0510201.java:16: 'class' or 'interface' expected
pubic class Application0510201{
^

Answer 1

DayOfWeek DayOfweek=new DayOfWeek();//对象肯定不能生成阿！你的构造函数是private！
你看看单例模式

Answer 2

package com.bb;import java.util.*;class DayOfWeek{
    private DayOfWeek(){
    }     public static final int SUNDAY=0;
     public static final int MONDAY=1;
     public static final int TUESDAY=2;
     public static final int WEDNESDAY=3;
     public static final int THURSDAY=4;
     public static final int FRIDAY=5;
     public static final int SATURDAY=6;
     
      public static void main(String[] args) throws Exception{
          Random  randomG=new Random();          for(int i=0;i<10;i++){
              int value =randomG.nextInt(7);
              DayOfWeek DayOfweek=new DayOfWeek();
              switch(value){
                  case  DayOfWeek.SUNDAY:
                     System.out.println("星期日");
                     break;
                  case  DayOfWeek.MONDAY:
                     System.out.println("星期一");
                     break;
                  case  DayOfWeek.TUESDAY:
                     System.out.println("星期二");
                     break;
                  case  DayOfWeek.WEDNESDAY:
                     System.out.println("星期三");
                     break;
                  case  DayOfWeek.THURSDAY:
                     System.out.println("星期四");
                     break;
                  case  DayOfWeek.FRIDAY:
                     System.out.println("星期五");
                     break;
                  case  DayOfWeek.SATURDAY:
                     System.out.println("星期六");           }
     }
  }
}

Answer 3

class DayoOfWeek{
private DayOfWeek(){
}瞪大眼睛，我的天，这种错误！

Answer 4

靠，这都没看出来
你的类如果要：DayOfWeek DayOfweek=new DayOfWeek();
那你的类的定义：class DayoOfWeek{
    private DayOfWeek(){
    }
就是错误的，那么private 改为public 就可以了这是个低级的错误哦

Answer 5

是这样的，我不清楚大家理解我没有我的意思是说我希望出现错误的提示，即编译时候提示DayOfWeek() has private access in DayOfWeek 
现在的程序是错误的，就是改为public后也是相同的错误
另外
To:jiang_xiao(原来秋天) 为什么你把外面的pubic class Application0510201去掉就正常了？

Answer 6

我知道去掉肯定是正常的，都在一个类里了，但是这样构造函数设置为private的提示也没有了，呵呵

Answer 7

呵呵，谢谢 yanxiazhiqiu的细心，我已经去掉那个小o了，不过还有一个地方有错误就是Application0510201.java:16: 'class' or 'interface' expected
pubic class Application0510201{
