java中饿汉式报错为啥

Question

public class propertise {
    public static void main(String[] args) {
//        Properties propertie= new Properties();
//        propertie.put("abc",15);
//        propertie.put("fgh",16);
//        propertie.put("uig",25);
//        propertie.remove("abc");
//        System.out.println(propertie);
        b s=b.getclas();
        System.out.println(s);


    }

}
class  b{
    private String  name;
     private static  b go = new b("小明");
    private b(String name){
        this.name=name;
    }

    public static b getclas(){
        return go;

    }

    @Override
    public String toString() {
        return "b{" +
                "name='" + name + '\'' +
                '}';
    }
}
