How to get enum values in capitalization-CodePudding

We create Enum classes and write all enum members in Full Uppercase.

public enum Color {
    RED,
    YELLOW,
    BLACK
}

How can we get the values in Capitalization (Writing the first letter of a word in uppercase, and the rest of the letters in lowercase) in java.

Meaning, when I fetch the Value of Color Enum, I should get as Red, Yellow, Black

CodePudding user response：

An enum can be more than just the simple constant as you have it in your snippet. Check out https://docs.oracle.com/javase/tutorial/java/javaOO/enum.html, especially the planet example.

So of course you can override the toString() method and whatever else you need to get your representation running.

If you want to use java enums name() method, you have no choice but to write the values in Capitalization in your code.

If you want to get a «display name» for each color, you can add a String field to your enum, like in the example below:

public enum Color {
    RED("Red"),
    YELLOW("Yellow"),
    BLACK("Black");

    String displayName;

    Color(String displayName){
         this.displayName = displayName;
    }
}

Then you can access the capitalized name with RED.displayName for example.

Last solution, you can manually capitalize the name, with the code below:

String str = RED.name();
String displayName = str.substring(0, 1).toUpperCase()   str.substring(1).toLowerCase();
