指定 enum 類型
===

public enum EnumTest {
    NAME_ONE("Name 1"),
    NAME_TWO("Name 2");

    private final String val;

    EnumTest(final String val) {
        this.val = val;
    }

    public String getVal() {
        return val;
    }
}

呼叫：

public class Test {
    public static void main (String args[]){
        System.out.println(EnumTest.NAME_ONE.getVal());
        System.out.println(EnumTest.NAME_TWO.getVal());
    }
}
