示例

public enum STUFF
{
    THING("Ok"), STUFF("Sweet"), PEOPLE("umm"), CAR("Vrrm");

    String contents;

    STUFF(String x)
    {
       contents = x;
    }

    {
        return ??
    }

System.out.print(STUFF.CAR.getContents());
//Vrrm

Answer 1

您应该查看行星示例:http://docs.oracle.com/javase/tutorial/java/javaOO/enum.html

public enum STUFF
{
    THING("Ok"), STUFF("Sweet"), PEOPLE("umm"), CAR("Vrrm");

    private final String contents;

    STUFF(String x)
    {
        contents = x;
    }

    public String getContents()
    {
        return contents;
    }
 }
