我有2个分类在不同的页面。Enum无法解析? Java
对象类:
public class Sensor {
Type type;
public static enum Type
{
PROX,SONAR,INF,CAMERA,TEMP;
}
public Sensor(Type type)
{
this.type=type;
}
public void TellIt()
{
switch(type)
{
case PROX:
System.out.println("The type of sensor is Proximity");
break;
case SONAR:
System.out.println("The type of sensor is Sonar");
break;
case INF:
System.out.println("The type of sensor is Infrared");
break;
case CAMERA:
System.out.println("The type of sensor is Camera");
break;
case TEMP:
System.out.println("The type of sensor is Temperature");
break;
}
}
public static void main(String[] args)
{
Sensor sun=new Sensor(Type.CAMERA);
sun.TellIt();
}
}
主要类:
import Sensor.Type;
public class MainClass {
public static void main(String[] args)
{
Sensor sun=new Sensor(Type.SONAR);
sun.TellIt();
}
错误有两个,一个是类型解决不了另一种是不倾斜导入。我能做什么?我第一次使用枚举,但你看到。
查看Reimeus的答案应该被接受(包含'enum'的类不能在默认包中)。或[看这里](http://stackoverflow.com/questions/283816/how-to-access-java-classes-in-the-default-package)。 – mins
