new A() vs. static new A()

Question

What is the difference from

class Test {
    A a = new A();
}

to

class Test {
   static A a = new A();
}

Does the virtual machine perform differently in the initialization?

Answer 1

In the first class there will be a member variable for each instance of the class Test. In the Second class there will be just one member variable for the whole class Test.
