is there premade function that gets mathematical Strings ( for example "(3+4+5)/sqr(20)") and returns result
Not built in to the Java language or SDK, but there's open source libraries such as https://github.com/sbesada/java.math.expression.parser that will do what you want.
-
Can't figure out "java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Double" error
You might then want to use some specific math parser Java library. E.g. this sbesada/java.math.expression.parser.
