java eclipse: public static void main(String args[])报错，请问怎么解决？

下面是下饭code内容
\

public static void main(String args[])throws java.io.IOExceptions{
    char c = (char)System.in.read();
    switch(c) {
        case'1':
            System.out.ptintln("your input is less than 3 MF");break;
        case'4':
        case'5':
        case'6':
            System.out.ptintln(c+">3");break;
        default://otherwise
            System.out.println(c);
    }
}

其实还有其他几个error也不知道怎么解决= =

= =xd,这code其实是书上抄的,就是一个检验输入的code(应该)

用这段代码：

Scanner scanner = new Scanner(System.in);
        String s = scanner.next();
        switch(s) {
            case "1":
                System.out.println("your input is less than 3 MF");break;
            case "4":
            case "5":
            case "6":
                System.out.println(s+">3");break;
            default://otherwise
                System.out.println(s);
        }

靓仔，你的主体类呢
