簡單的規則：無法解析aNewRulesEngine（）

Question

下面的代碼不能被編譯由於「找不到符號 符號：類aNewRulesEngine 位置：類org.jeasy.rules.core.RulesEngineBuilder」

然而，判斷通過本教程https://github.com/j-easy/easy-rules/wiki/fizz-buzz它應該沒問題。

任何想法爲什麼它會變酸？

import org.jeasy.rules.api.RulesEngine; 
import org.jeasy.rules.core.RulesEngineBuilder; 

public class Main { 

    public static void main(String[] args) { 
     RulesEngine rulesEngine = new RulesEngineBuilder.aNewRulesEngine(); 
    } 
} 

Answer 1

aNewRulesEngine是RulesEngineBuilder一個靜態方法（根據文檔：https://github.com/j-easy/easy-rules/blob/master/easy-rules-core/src/main/java/org/jeasy/rules/core/RulesEngineBuilder.java） - 但你的代碼示例中，你也試圖實例化RulesEngineBuilder一個實例。

也許這代碼將更好的工作：

import org.jeasy.rules.api.RulesEngine; 
import org.jeasy.rules.core.RulesEngineBuilder; 

public class Main { 

    public static void main(String[] args) { 
     RulesEngine rulesEngine = RulesEngineBuilder.aNewRulesEngine(); 
    } 
}
