Java-范圍內沒有任何封閉類型的實例…

Question

我有這個課：

public class PetAssembly extends Global
{
    public Socket socket;
    public ConnectionManager user;

    public PetAssembly(Socket socket, ConnectionManager user)
    {
        this.socket = socket;
        this.user = user;
    }

    public void initPet()
    {
        sendPacket(socket, "0|PET|I|0|0|1");
        sendPacket(socket, "0|PET|S|1000|1|0|8000|50000|50000|1000|1000|50000|50000|" + (((user.user.getSpeed() * 30) / 100) + user.user.getSpeed()) + "|testPet");
    }
}

我要使用它：

case "/pet":
      PetAssembly.this.initPet();
break;

但這給了我這個錯誤，如何解決？ 我是一個初學者：作用No enclosing instance of the type PetAssembly is accessible in scope

PetAssembly.initPet（）是一個實例方法。 您首先需要構造一個PetAssembly對象（該類的實例），然后對該對象進行引用，然后才能在該對象上調用方法。

PetAssembly pa = new PetAssembly(socket, user); 
// Creates a new PetAssembly object
// and stores a reference to that in the variable pa.
pa.initPet(); 
// Calls the initPet() method on the PetAssembly object referred to by the variable pa.
