Program/Source Code:

The source code to implement static block with Instance Initializer Block is given below. The given program is compiled and executed successfully.

// Java program to implement static block with 
// Instance Initializer Block

class Sample {
  static {
    System.out.println("Static block called");
  }

  {
    System.out.println("Instance initializer block called");
  }

  Sample() {
    System.out.println("Constructor called");
  }

}

public class Main {
  public static void main(String[] args) {
    Sample S = new Sample();
  }
}

Output:

Static block called
Instance initializer block called
Constructor called

Explanation:

In the above program, we created two classes Sample and Main. The Sample class contains a Static Block, IIB (Instance Initializer Block), and a constructor.

The Main class contains a method main(). The main() method is the entry point for the program, here we created an object of the Sample class called static block, IIB, and constructor of the class.
