选择正确的资源包：JAVA SE 8

如何解决选择正确的资源包：JAVA SE 8

我有以下 3 个属性文件

RB_en.properties

ride.in=Take a ride in the
    

RB_en_US.properties

elevator=elevator
    

RB_hi_IN.properties

elevator=lift

---

我的系统默认语言环境是 := en_US

---

我的代码是

// BundleTest.java
import java.util.*;

class BundleTest {
    public static void main(String ... args){
        Locale l = new Locale("hi","IN");
        ResourceBundle rb = ResourceBundle.getBundle("RB",l);
        
        System.out.println(rb.getobject("ride.in") + " " + rb.getobject("elevator"));
    }
}

---

预期输出 :=

Take a ride in the lift

---

但我遇到以下错误：=

Exception in thread "main" java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle,key ride.in
        at java.util.ResourceBundle.getobject(UnkNown Source)
        at BundleTest.main(BundleTest.java:9)
