Question

What will be the result of compilation and execution of the following code:


public class Test {
    static int b = Test.a;
    static int a = 3;
    static {
       System.out.println("a=" + a + ", b=" + b);
    }
}

Choose all that apply.

The static initializers and class variable initializers are executed in textual order, and may not refer to class variables declared in the class whose declarations appear textually after the use, even though these class variables are in scope (§8.3.2.3). This restriction is designed to detect, at compile time, most circular or otherwise malformed initializations.

( JLS 12.4.1)
