Mastering Java: The Ultimate Quiz for 'Thinking in Java'

Which of the following is true about the order of initialization in Java?

1. Static blocks are initialized before instance blocks.

2. Instance blocks are initialized before constructors.

3. Constructors are initialized before static blocks.

4. Instance variables are initialized after constructors.

The correct answer is: Static blocks are initialized before instance blocks.

In Java, static blocks are initialized before instance blocks, which means that they are executed before instance blocks when a class is first loaded into the Java Virtual Machine. This makes option A the correct answer. Option B, on the other hand, is incorrect because instance blocks are actually executed before constructors. Option C is incorrect because constructors are initialized after static blocks. Option D is incorrect because instance variables are actually initialized before constructors.
