Generating an array from enum values

Question

Let's say I have an enum as such:

public enum Fruit {
    APPLES("Apples"),
    BANANAS("Bananas"),
    PEAR("Pear"),
    ORANGE("Oranges");

    private final String string;

    Fruit(String string) {
        this.string = string;
    }
}

What would be the best way to generate a String[] array containing the string values of the enum, ie "Apples", "Bananas, "Pear", "Oranges"

I can think of a few ways but they could get messy and I'm wondering if there is a direct way to get these values.

Answer 1

Here's the shortest one I could come up with:

Arrays.stream(Fruit.values()).map(Fruit::getName).toArray(String[]::new);

Fruit.getName() would be a method returning the string field in the Enum

Answer 2

你可能会做这样的事情。

Arrays.toString(Fruit.values()).replaceAll("^.|.$", "").split(", ");
