在Java中你可以:

public enum Enum {
    ONE {
        public String method() {
            return "1";
        }
    },
    TWO {
        public String method() {
            return "2";
        }
    },
    THREE {
        public String method() {
            return "3";
        }
    };

    public abstract String method();
}

你是如何在Scala中做到这一点的？

使用java多年后,我试图进入scala.可以说我有一个像这样简单的枚举

public enum Foo{
  Example("test", false),
  Another("other", true);

  private String s;
  private boolean b;

  private Foo(String s, boolean b){
    this.s = s;
    this.b = b;
  }

  public String getSomething(){
    return this.s;
  }

  public boolean isSomething(){
    return this.b;
  }
}

随着文档和stackoverflow的一些帮助,我得到了:

object Foo extends Enumeration
{
  type Foo = Value
  val Example, Another = Value

  def isSomething( f : Foo) : Boolean = f match {
    case Example => false
    case Another => true
  }

    def getSomething( f : Foo) : …
