Initialize final variable before constructor in Java

by

I do not really understand your question. That

public class Test3 {
    private final String test = "test123";

    public Test3() {
        System.out.println("Test = "+test);
    }

    public static void main(String[] args) {
        Test3 t = new Test3();
    }
}

executes as follows:

$ javac Test3.java && java Test3
Test = test123
