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 found the better solution. This can be achieved through RegEx:

if (str.matches("val1|val2|val3")) {      // remaining code } 

For case insensitive matching:

if (str.matches("(?i)val1|val2|val3")) {      // remaining code }
