I may get result of any of the type , so i am defining enum this way
public enum Result
{
1, 2,3, 4,5, 6,7, 8
}
String resultvalue = calculateResult();
switch (Result .valueOf(resultvalue ))
{
}
But i am geting error at the Enum Declaration itself saying Mispalced Constructors .
Could anybody please help me
Those aren't valid identifiers for enum values, basically. You'll need to prefix them with a letter or _. You'll also need to make the identifiers unique - currently you've got 0010
four times...
Once you've sorted that out, the rest should probably be okay - but if you have any more problems, please post a short but complete program, rather than snippets.
0001
is not a valid Java identifier. A Java Identifier must not start with a digit.
Although I don't understand what you want to achieve and why you have duplicates. Something like that (maybe using an int instead of String) should work.
public enum Result {
One( "0001"),
Two( "0010")
...
private String val;
private Result(String val) {
this.val = val;
}
}
I an not sure why calcuate result would return a String. I would return a int here but...
String resultvalue = calculateResult();
switch (Integer.parseInt(resultvalue)) {
case 0b0001:
case 0b0010:
case 0b0110:
case 0b1010:
case 0b1100:
}
What is it that you are trying to achieve? If you need to:
then you don't need an enum. Just do it with Integer.parseInt()
, Set.contains()
, and switch
.
