Compare one String with multiple values in one expression

Question

I have one String variable,

str

with possible values,

val1

,

val2

and

val3

.

I want to compare (with equal case)

str

to all of these values using an if statement, for example:

if("val1".equalsIgnoreCase(str)||"val2".equalsIgnoreCase(str)||"val3.equalsIgnoreCase(str))

{

      //remaining code

}

Is there a way to avoid using multiple OR (||) operators and compare values in one expression? For example, like this:

 if(("val1" OR "val2" OR "val3").equalsIgnoreCase(str)   //this is only an idea.

Answer 1

I have found better solution this can be achieve using reg-ex -

   str.matches("val1|val2|val3");

For case insensitive matching:

   str.matches("(?i)val1|val2|val3");
