Can anyone guide me on implementing map key autocomplete in Java?

Looking to transform this Typescript code into Java. Here's the code snippet:

type CompTypes = "Texture" | "Layer" | "Sound";
Map<CompTypes, Component> components;

Any suggestions on how to achieve this in Java?

Answer №1

To implement a system for different types of components, one approach is to use an enum called CompTypes:

public enum CompTypes { Texture, Layer, Sound };

Next, create a class named Component with the desired structure.

Then, construct an EnumMap where CompTypes serves as the key and Component serves as the value:

EnumMap<CompTypes, Component> enumMap = new EnumMap<CompTypes, Component>(CompTypes.class);

You can insert a new pair into the map:

enumMap.put(CompTypes.Layer, new Component());

Retrieve an existing pair like this:

enumMap.get(CompTypes.Layer)
