求高手打救，关于包间互相调用的问题....

[正在努力的PP君]

关于命令模式的。
这是部分：

package Body;
public class SimpleRemoteControl {
	Command slot;
	
	public SimpleRemoteControl(){};
	public void setCommand(Command command){
		slot=command;
	}
	
	public void buttomWasPressed(){
		slot.execute();
	}
}

package AllCommand;
import function.AR;
public class OffARCommand implements Command {
	AR ar;	
	
	public OffARCommand(AR ar) {
		this.ar=ar;
	}
	
	public void execute(){
		ar.OffAR();
	}

}

import AllCommand.*;
public class OrderPattern{
    
    public static void main(String[] args) {
    	
      SimpleRemoteControl remote = new SimpleRemoteControl();
      AR ar=new AR();
      OffARCommand OffAR=new OffARCommand(ar);
      
      
      remote.setCommand(OffAR);
      remote.buttomWasPressed();
    
    }
}

我在编译的时候出现了：
“无法将 Body.SimpleRemoteControl 中的 setCommand(Body.Command) 应用于 (AllCommand.OffARCommand)
remote.setCommand(OffAR);
^
1 错误

Process completed.
”

求高手请教......

public class OffARCommand implements Command {
这里的Command 接口和
public class SimpleRemoteControl {
Command slot;
这里的Command是同一个类吗

[正在努力的PP君]

是的,是同一个类！

[德薄才浅]

 public static void main(String[] args) {
        
      SimpleRemoteControl remote = new SimpleRemoteControl();
      AR ar=new AR();
      Command OffAR=new OffARCommand(ar);//如果这句编译出错，那可能是导错包了（Command）
      
      
      remote.setCommand(OffAR);
      remote.buttomWasPressed();
    
    }
