This is unrelated to Threads, so I'm moving it to Java in General(Beginner).

Try some of these ...

A static block can initialize static variables.

The variable declaration can include initial values.

The variable declaration can call a method. I just tried this for the first time.

String var = getVar();

A method like getVar must be very careful not to assume the object instance is fully initialized, eg passing a reference to "this" to some other object might get you in trouble.

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
