Java Program Structure-CodePudding

I am building an app where I print a word in different languages based on a user's selection from a dropdown menu. My current method works however is not efficient as I am getting the data from a nested class and requesting it from a completely different class which requires a line of code for each word in a nested class. How can I achieve this in a more efficient/easier way? Here is the basic format of said code:

public class words {

   class example {
       String english = "example";
       String chinese = "example_in_chinese";
   }

   class example2 {
       String english = "example2";
       String chinese = "example2_in_chinese";
   }
}


public class getWords {

    words word = new words();
    words.example example = word.new example();
    words.example2 example2 = word.new example2();

    */ I have to repeat the above line for each of the 20 
    words I have in a nested class
    /*

}

Maybe you can use chain of responsibility design pattern to determine which language is appropriate to print.

It takes long to show with code but I will given hint to you.

Iterate over objects to find printable language with given dropdown value. If you can not find appropriate language for printing then ignore it.

I think you can try to use Map.

public class Words {
    static Map<String, String> example1 = new HashMap<String, String>();
    example1.put("english", "example");
    example1.put("chinese", "example_in_chinese");

    static Map<String, String> example2 = new HashMap<String, String>();
    example2.put("english", "example2");
    example2.put("chinese", "example2_in_chinese");
}

So you can just call

Words.example1.get("english");

Or even further, you can create an enum Language

enum Language {
    ENGLISH, CHINESE
}

public class Words {
    static Map<Language, String> example1 = new HashMap<Language, String>();
    example1.put(Language.ENGLISH, "example");
    example1.put(Language.CHINESE, "example_in_chinese");

    static Map<Language, String> example2 = new HashMap<Language, String>();
    example1.put(Language.ENGLISH, "example2");
    example1.put(Language.CHINESE, "example2_in_chinese");
}

Words.example1.get(Language.ENGLISH);

Just to reduce typing error possibility.
