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

In which order are fields initialized?

1. In the order they appear in the class

2. Alphabetically

3. In the order they are used

4. Static fields first, then instance fields

The correct answer is: In the order they appear in the class

Fields are variables declared within a class and can be of different types such as int, string, boolean, etc. When a class is instantiated (i.e. an object is created from that class), the fields are initialized, meaning they are given a specific value or default value. In this context, "order of initialization" refers to the order in which fields are given their initial values. The correct answer is A because fields are initialized in the same order they appear in the class. This means that the first field declared in the class will be initialized first, followed by the second, and so on. The other options, namely B, C, and D, do not accurately reflect the process of field initialization. Field initialization is not done alphabetically or based on the usage of fields within the class. Additionally, static fields, which are shared by all instances of a class, are not necessarily
