static variable initialization java

Question

how to initialize a private static member of a class in java.

trying the following:

public class A {
   private static B b = null;
   public A() {
           


        

Answer 1

Your code should work. Are you sure you are posting your exact code?

You could also initialize it more directly :

    public class A {

      private static B b = new B();

      A() {
      }

      void f1() {
        b.func();
      }
    }

Answer 2

The preferred ways to initialize static members are either (as mentioned before)

private static final B a = new B(); // consider making it final too

or for more complex initialization code you could use a static initializer block:

private static final B a;

static {
  a = new B();
}
