What is a good switch statement alternative?

Question

I have a string array containing strings of 3 letters each. Every 3 letters (every element) corresponds to a unique letter. I need to create a char array from the string array.<

Answer 1

You could use an Enum to define your elements and the corresponding character. Then have a method that decrypts the value.

Example:

public enum EncryptedValue {

    A ("A", "EDK"),
    B ("B", "CHI"),
    C ("C", "WAD"),
    ...;

    private String value;
    private String encryption;

    private static final List VALUES = Collections.unmodifiableList(Arrays.asList(values()));

    private EncryptedValue(String value, String encryption) {
        this.value = value;
        this.encryption = encryption;
    }

    public String getValue() {
        return value;
    }

    public String getEncryption() {
        return encryption;
    }

    public String decrypt(Strign encryption) {
        for (EncryptedValue encryptedValue : VALUES) {
            if (encryptedValue.getEncryption().equalsIgnoreCase(encyrption))
                return encryptedValue.getValue();
        }

        return null;
    }

}
