Java interface problem

The company is working on a. net project now, and there is no Eclipse in the computer. I made it with a notepad. There may be a slight compilation error, fine-tune it yourself.

Interface weather conditions {

void showState()；

}

Class weather {

WeatherState state = null

Public weather () {

}

Public Weather (Weather Status) (

this.state = state

}

Public display () {

state . show state()；

}

}

Class Fine implements WeatherState {

Public void showState(){

system . out . println(" clear ")；

}

}

Class Rain implements WeatherState {

Public void showState(){

system . out . println(" rain ")；

}

}

Public class Main {

Public static void main(String[] args) {

WeatherState state 0 1 = new Fine()；

WeatherState state 02 = new Rain()；

Weather = new weather (state 01); //You can insert 0 1 or 02 in brackets.

weather.show()。

}

}
