Complete Java SE 8 Developer Bootcamp - Static Initialization Block

The video tutorial explains static initialization blocks in programming, highlighting their execution when a class is loaded, unlike regular initialization blocks that execute with each object instantiation. It discusses the limitations of static blocks, such as their inability to access instance variables or methods, and clarifies that static blocks can be repeated and executed in order. The tutorial emphasizes the importance of understanding static context and its constraints.

What is the main difference between static and regular initialization blocks?

• Static blocks execute once when the class is loaded.

• Regular blocks cannot access static variables.

• Static blocks execute every time an object is created.

• Regular blocks execute once when the class is loaded.

Why can't a static block access the 'color' field in the example?

• Because 'color' is a private field.

• Because 'color' is a static field.

• Because 'color' is not declared.

• Because 'color' is a non-static field.

What happens if you try to call an instance method from a static block?

• The method will be ignored.

• The method will execute but with default values.

• An error will occur because there is no object instance.

• The method will execute normally.

Can you have multiple static initialization blocks in a class?

• No, only one static block is allowed.

• Yes, but only two are allowed.

• Yes, but they execute in reverse order.

• Yes, and they execute in the order they are defined.

What is the purpose of using static initialization blocks?

• To execute code every time an object is created.

• To override instance methods.

• To initialize static state.

• To initialize instance variables.
