Initialize final variable before constructor in Java

Question

Is there a solution to use a final variable in a Java constructor? The problem is that if I initialize a final field like:

private final String name = \"a na         


        

Answer 1

Another possiblity is to initialize the field in an instance initializer blocK:

public class Foo {
        final String bar;

        {
                System.out.println("initializing bar");
                bar = "created at " + System.currentTimeMillis();
        }

        public Foo() {
                System.out.println("in constructor. bar=" + bar);

        }

        public static void main(String[] args) {
                new Foo();
        }
}
