@Override
public
void show() {
System.out.println("前");
}
},
BEHIND("后") {
@Override
public
void show() {

}
},
LEFT("左") {

private String

private Direction3(String name){
this.name = name;
}

public String getName() {
return
name;
}

public
abstract void show();
}

public
classDirectionDemo {
public
static void main(String[] args) {

Direction3d3 = Direction3.FRONT;
System.out.println(d3);
System.out.println(d3.getName());
d3.show();
System.out.println("--------------");

Direction3dd = Direction3.FRONT;
dd= Direction3.LEFT;

switch (dd) {
case
FRONT:
System.out.println("你选择了前");
break;
case
BEHIND:
System.out.println("你选择了后");
break;
case
LEFT:
System.out.println("你选择了左");
break;
case
RIGHT:
System.out.println("你选择了右");
break;
}
}
}

运行结果：

FRONT
前
前
--------------
你选择了左
