Java-范围内没有任何封闭类型的实例…

Question

我有这个课：

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;

但这给了我这个错误，如何解决？ 我是一个初学者：作用No enclosing instance of the type PetAssembly is accessible in scope

PetAssembly.initPet（）是一个实例方法。 您首先需要构造一个PetAssembly对象（该类的实例），然后对该对象进行引用，然后才能在该对象上调用方法。

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.
