Object of the class as instance variable inside the class [duplicate]

Answer 1

Re question 2 - if you run this code, you get a StackOverflowException => Yes it creates an inifinite number of objects (well it tries...)

public class Test2 {

    private Test2 subject = new Test2(); //Create Test2 object in Test2

    public static void main(String[] args) throws Exception {
        Test2 t = new Test2();
    }
}
