Java anonymous code blocks

Question

What is the advantage of using anonymous blocks in Java?

public static void main(String[] args) {
    // in
    {
        // out
    }
}

Answer 1

The anonymous code blocks in Java are used to restrict variable scope.

public void foo()
{
    {
        int i = 10;
    }
    System.out.println(i); // Won't compile.
}
