What are initialization blocks in Java?

Initialization blocks in Java are used to initialize instance variables. They can be instance initialization blocks or static initialization blocks.

Can you give me an example of an instance initialization block?

Sure! Here's an example:

class Example {
    int x;
    {
        x = 10; // instance initialization block
    }
}

What about static initialization blocks?

Static initialization blocks are used to initialize static variables. Here's an example:

class Example {
    static int x;
    static {
        x = 20; // static initialization block
    }
}

When are these blocks executed?

Instance initialization blocks are executed when an instance of the class is created, while static blocks are executed when the class is loaded.
