}

public class Test{
//  private static final Myclass object1;编译不通过，必须赋初值，或者在静态语句块中赋值。
    private static final Myclass object2=new Myclass("2");
    private final Myclass object3;//这个finally不是很清楚
    static{
        object1 = new Myclass("1");
        Myclass object4 = new Myclass("4");//要加Myclass
    }

    public Test(){
        Myclass object3 = new Myclass("5");//要加Myclass
    }

    {
        object3 = new Myclass("3");//如果注掉这句，构造方法会报错。放在构造方法也可。
        Myclass object6 = new Myclass("6");//要加Myclass
    }

    public static void main(String args[]){
        new Test();
    }
}
class Myclass{
      Myclass(String i){
      System.out.println(i);
      }
}

------解决方案--------------------
class Myclass{
 Myclass(int i){
 System.out.println(i);
 }
}
public class Test{
   //private static final Myclass object1;//这行必须给出初始值   因为有final否则编译失败
   private static final Myclass object2=new Myclass(2);
   //private final Myclass object3;//同上
      
   static{
       Myclass object4=new Myclass(4);
   }

   public Test(){
      Myclass object5= new Myclass(5);
   }

   {
      Myclass object6=new Myclass(6);
   }

   public static void main(String args[]){
       new Test();
   }
}
如果把那两条注释掉则输出为2 4 6 5
