Oct 18, 2022 · Instance Initialization Blocks or IIBs are used to initialize instance variables. So firstly, the constructor is invoked and the java compiler copies the instance initializer block in the constructor after the first statement super().

Aug 13, 2013 · This is because in Java, instance variables, which are variables that reside within a class, but not a method, do not have to be manually initialised. In Java, when declaring instance variable(s), if no value is given, the compiler will apply a default value to allow the program to run.

Sep 6, 2012 · When does the instance variable get initialized? Is it after the constructor block is done or before it? Consider this example: public Parent(){ System.out.println("Parent Constructor"); init(); public void init(){ System.out.println("parent Init()"); super(); System.out.println("Child Constructor"); System.out.println("Child init()");
