枚举构造函数中的Java字节类型

Question

public enum Rank {
    TEN("Ten",1),
    NINE("Nine",2),
    EIGHT("Eight",0),
    SEVEN("Seven",0);


    private final String name;
    private final int point;

    /*
     * @param rank should be byte
     */
    private Rank(String name,int point)
    {
        this.name=name;
        this.point=point;
    }

如何将int替换为byte.我能想到的一种方法是使用TEN("Ten",Byte.parseByte("1"));

有没有更好或更短的方法？

Answer 1

刚刚cast到byte,像这样:

public enum Rank {
    TEN("Ten", (byte)1),
    NINE("Nine", (byte)2),
    EIGHT("Eight", (byte)0),
    SEVEN("Seven", (byte)0);


    private final String name;
    private final byte point;

    private Rank(String name, byte point)
    {
        this.name = name;
        this.point = point;
    }
